SuperBowl XL Copy Protected ?!

[Photoguy]

Is there any way to get around CPRM copy protection? I recorded SuperBowl XL on a standalone DVD recorder and when I tried to play the finalized disc on my computer, only the first 10 minutes would play with PowerDVD. I used Windows Explorer to look at the contents of the disc. Even though Explorer reports that the disc size is 4.11 GB, there are only 2 vobs. Video_TS.vob is 140 KB (the menu) and VTS_01_1.vob is 146,164 KB.

The disc contains and plays the entire 4 hours on the original DVD recorder and also on a regular standalone DVD player.

I ran the disc through DVD Decrypter and it errors out with:

“Unable to create, replace or append to file C:\DVD_Video_Recorder\Video_TS\
Reason: The system cannot find the path specified”

Here is the relevant portion of Decrypter’s log file.

I 11:27:30 Found 1 CD-RW and 1 DVD±RW!
I 11:27:35 Operation Started!
I 11:27:35 Source Device: [0:0:0] LITE-ON DVDRW SOHW-1213S TS05 (R:)

Any help appreciated.

Hi!

Is there another folder on the disc, with ".VRO" files in it?

If so, they can be read by "TMPGEnc DVD Author". You can obtain a FULLY functional free 30 day trial version of this commercial program at:

[Photoguy]

Thanks for the reply, but no, there is only the one folder on the disk, the standard Video_TS folder and in that folder are:

Video_TS.bup
Video_TS.ifo
Video_TS.vob
VTS_1_0.bup
VTS_1_0.ifo
VTS_1_0.vob

That's it. I've seen .vro files on recordings on DVD-RAM discs, but this is a DVD-RW disc formatted in Video Mode, not VR mode.

I believe that someone hit the "STOP" button sometime during the game. There is no CPRM transmitted on broadcasts.

[Photoguy]

If you would look at the DVD Decrypter log I posted you will see that it is in fact using CPRM copy-protection. I will re-quote the line again:

I 11:27:35 Source Media Copyright Protection System Type: CPRM

It is also in the owner's manual of my DVD recorder that broadcast programs that use CPRM and are set to allow a one-time-copy of that broadcast. My recorder is a Panasonic DMR-ES20.

If I hit the stop button as you claimed then how come I can watch the entire game on that DVD? I just can't make a copy of it on my computer.

This may be of interest http://www.casualtek.com/2006/01/12/you-like-drm-youll-enjoy-cprm/

If you have an old DVD-Rom (player only), you should be able to "see" all of the files.

2nd possiblility: Install WinDVD or PowerDVD, then install GraphEdit. You might be able to construct a "graph" to save the output to disk.

For future: Find a capture card that doesn't "understand" the CPRM encoding.

No doubt that this will be a problem for anyone that records content on newer hardware.

Thanks guys for all your help. I did some experimenting today and I was very surprised and happy to discover that DVD Shrink was able to scan and rip the entire disk. I now have a copy of the disk that is showing as complete and plays on my computer.

Just for your information, I downloaded and tried a program called ISOBuster. It also displayed the missing files and if I bought it for $29.00, claimed it would extract those files for me. I tried Shrink and it worked so there was no need to buy ISOBuster.

Again, thanks for your replies.

[setarip_old]

Congratulations on resolving your dilemma!

However, I find it quite curious that DVD Shrink, with a built-in ripper far inferior to that of DVD Decrypter, was able to "see" additional files.

May I ask:

1) Was there a second folder on the disc (that only DVD Shrink "saw")?

2) What were the names of the additional files?

[hartford]

@ photoguy

Well, I'm suprised and pleased at your discovery.

Thanks for that info.

[Photoguy]

Congratulations on resolving your dilemma!

1) Was there a second folder on the disc (that only DVD Shrink "saw")?

2) What were the names of the additional files?

1 - Although Shrink must have "seen" the additional folder, it only displays "Title Menus and Main Movie"

2 - ISOBuster showed an additional folder named "Video" with another "Video_TS" folder in it. In that folder there were all the .ifo, .bup and .vob files that make up the full disc.

I have screen shots of Windows Explorer, Decrypter, ISOBuster and Shrink accessing this disc. If you are interested in seeing these various views, let me know.

[setarip_old]

Check your Windows settings - to make sure Explorer is set to show ALL files and extensions, including "hidden" files and folders...

I already have all my computers set to "Show Hidden Files and Folders" and also have the "Hide Protected Operating System Files" unchecked. I like to know what's going on on my computers at all times :)

Here are the Explorer and ISOBuster views of the DVD.

I posted the pictures on alt.binaries.test if you use newsgroups. They are from Photoguy with a subject name of DVD Screen Shots

[bongoman31]

I copied the game, also with a DVD recorder. But I lost interest in it, when a) it wasn't that great of a game, and b) there was a lip sync. problem on every shot that showed John Madden or Pam Oliver, and probably Mick Jagger. The audio and video was a second or two out of sync. You'd think in this day and age ABC could do a broadcast like that with out it looking like they were broadcasting from Antartica!

[Photoguy]

I think the audio/video sync problems were caused by their attempt at time delaying the broadcast in case there were any "wardrobe malfunctions" or "speech malfunctions". I've seen the same audio sync problems on other network programs that my local stations are feeding to the cable company via digital transmission. In fact, my local cable company dropped the digital feed of one local TV station and reverted back to analog because they had so many problems. It makes you wonder if the switch to all digital in 2009 is going to be a good thing or bad.

Next time I record an event like this, I am going to try my other DVD recorder that records to DVD+R(W)'s because from what I've read, the +R format does not support CPRM. I'll either get a copyable disc or the dreaded "This content is copy protected and cannot be recorded" message.

[setarip_old]

@Photoguy

I finally got to see your posted images here. I'm still of the opinion that your Windows settings were such that Explorer did not display the (I'm presuming, "hidden") folder named "Video" that appears in the ISOBuster screengrab.

Whatever the case was, your idea of using your other recorder makes excellent sense ;>}

I understand why you might think that. I’ve seen so many posts here from people who overlook the obvious and are asking “newbie” questions. I can assure you that I am a very experienced computer user and know the how to display hidden files and folders. I have had a “home computer” since 1982 when they first came out and was the SYSOP of a BBS from 1985-1992. (You remember those?).

But, in case you are still skeptical, I will attach proof which you can see for yourself whenever the attachment gets approved.

Since my last message here I tried playing the DVD in my Toshiba laptop and when WinDVD launches, it says “Your DVD player does not support CPRM.. Protected content will not be displayed”

I have already figured out how to beat CPRM on my DVD recorder, so I only post this information because I believe it will become more of an issue in the future.

[setarip_old]

a BBS from 1985-1992. (You remember those?)I spent many a night (And MANY dollars in phone bills) with my 75 baud acoustic coupled modem allowing me to painstakingly communicate with, and download teensy-weensy programs from, BBSs ;>}

I case you still don't believe me, I will attach DVD Decrypter and DVD Shrink's views of the same DVD.

[setarip_old]

It's not that I don't believe you, it's more that the overall scenario is hard to accept. If the files you were finally able to extract with ISOBuster actually played, it's hard to believe that CPRM protection was used.

Read the following article describing how CPRM works and I think you'll understand what I'm getting at:

http://www.schneier.com/crypto-gram-0102.html#1

Also, if you'd care to placate an old man, would you see what happens if you access the original disc with NERO Burning ROM v.6.xxx. I believe it may show this "very hidden" folder and its contents.

P.S. Let's hope your latest screengrabs become available for viewing shortly ;>}

**EDIT** I just came across the following information regarding WinDVD Platinum/7: CPRM Support
You can now watch CPRM-protected video content with WinDVD. WinDVD fully supports CPRM and has the ability to play CPRM-protected discs or video content. CPRM is a video content protection mechanism aiming to prevent the content that you record through TV broadcasting from being copied or reproduced by any means.

This has nothing to do with your question, but I also have a 1213S and your firmware is waaaaaaay out of date.
The latest is TS0J and can be found here (http://forum.rpc1.org/dl_firmware.php?download_id=1862). :)

Using Nero 6.6.0.16, the disc info says the disc is 4247 MB UDF/ISO 9660 Mode 1.

When creating a new compilation and selecting the DVD in question as the source for the files, the File Browser in Nero only shows the same 6 files that Windows Explorer shows as being on the disc.

I decided to try and use Nero’s copy disc function (copy as an image to the HD and burn to a new disc) and it worked. Nero copied the entire disc. The copy was identical to the original, as expected, and the “missing files and folders” on the original were “missing” on the copy making it impossible to edit with Recode.

I know all of this is sounds incredible, but it is true. It also looks like CPRM copy protection as currently implemented on digital broadcasts isn’t very effective if Nero can make a straight copy of the disc.

Thanks WarDog, I am leery of flashing the DVD-RW drive as the last time I did that with a Sony drive, it could no longer erase or write to many (but not all) of the Sony DVD+RW's that I had and had been using very successfully up to that point. It did make burning to DVD-RW's at 4x possible though.

[WarDog]

Really nothing to flashing the drive. Just make sure all programs are closed, screen saver off and run flash program and don't turn off computer. It only takes a few seconds and then you will reboot your system for the the update to take effect. The update helps for new media(s) and so forth.

[setarip_old]

@Photoguy

Not to belabor the issue (since you've already succeeded at finding a way to backup the files) but, the screengrab of your DVD Decrypter effort is perplexing to me.

Do/Did you, in fact have, have a folder named "DVD_Video_Recorder" and a sub-folder in it named "VIDEO_TS" residing on your "H:\" drive" (presumably hard drive or hard drive partition)? The error generated by DVD Decrypter has nothing to do with its ability to READ from the DVD, it has to do with its inability to WRITE to your hard drive...

[Photoguy]

Setarip_old

As I'm sure you know but maybe forgot, when you run DVD Decrypter in File mode, it automatically selects the following locations and names to rip a disc.

It selects the hard drive with the most free space on it. In my case that would be my "H:" partition.

It creates a folder to rip into based on the label or title of the DVD. All DVD's created on my Panasonic DVD recorder have the label or title of "DVD_Video_Recorder. So, therefore DVD Decrypter creates a folder with that name.

It also creates a sub-folder in the main folder named Video_TS in which all the ifo's, bup's and vob's are written to.

So the answer is yes, that folder existed. After hitting "Cancel" from the error message you see in the Decrypter screen shot, the other 5 files are ripped to the folder in question.

The main point is that Decrypter doesn't see all the folders and files that show up in ISO Buster. It only sees the files that you can see with Windows Explorer. DVD Shrink, on the other hand, can find the whole disc.

I may just have to go out and purchase a tabletop recorder, just to record and explore such a DVD ;>} Take care!

You take care also. I really appreciate you taking the time and effort to try to help me figure this really weird situation out.

By the way, you do outdate me. My first modem was a 300 baud connected to the RS232 port on the expansion case of my TI99 4/A computer (which I still have)!
