Backing Up Dual Layer DVD+R

[Leica]

I have a couple of DVDs on my hard drive that I want to burn to a blank DVD+R Dual Layer blank disk.

My original DVDs are sracthed and no longer accessable. So I can't rip them anymore.

When I ripped these DVDs to my hard drive, I used SmartRipper and copied all the files (not a movie rip). So in my folder I have ALL the original IFO, BUP and VOB files, identical to what would be on the original DVD. I can play these DVDs using PowerDVD just fine.

So can I just burn these files to a blank DVD+R using Nero? That is, I put them in a folder called VIDEO_TS, just like I do for single layer DVDs?

Thanks.

i cannot recall where i read it, but i was under the impression that nero was not very good at handling dual layer burning.
personally i would use pgc_edit to create an iso of your files and burn using dvd decrypter.
cheers

No doubt about it. Use PgcEdit - guide (http://www.videohelp.com/~r0lZ/pgcedit/third_party/blutach/dl_burning_with_pgcedit.htm).

My opinion of Nero is well known - it's not good for much except generating revenue for Nero!

Use Verbatim 2.4x +R DLs. Don't forget to set the booktype to DVD-ROM.

Just for my future reference (When dual layer disks drop in price), is this method far superior to using Shrink to create iso, and burn with Decryptor?

Thanks guys. I read the guide for PgcEdit. My GOD that's a lot of work!!!

I am so used to using Nero and it is so easy and flawless with single layer media. It takes a few seconds to start the burning process! Are you sure it is useless for dual layer media???

By the way I already ordered my media. A 25 spindle of Memorex 2.4x for $67.50 delivered from buy.com - they have a special this week for $75 and I used a 10% off coupon.

So $2.70 (per disc) is the cheapest I could find for dual layer media. I figured Memorex can't be bad. How much are the Verbatim? I remember a few months ago they were like $10 each!

Shrink is not needed. If the disc is going to be an exact duplicate then just use DVD Decrypter in ISO read/write mode.

If Shrink is going to be used. Make sure the layer break/change removal is unticked. Shrink could be used to make movie only DL discs.

BTW, Dual Layer is now belongs to DVD-R. Double Layer is DVD+R. I know people who have bought DL DVD-R thinking they will work in a DL DVD+R only drive.

I have 100% success with Datasafe DL media with a Pioneer 109. They work out at £2 each where I am.

bongoman31 - sorry but using DVD Shrink to turn a 8GB DVD into 4.5GB makes the quality unwatchable! I have tried it and it is terrible. I guess for people who watch on 13" TV's from a distance of 50 yards or more, its OK. But not for me!!!

Have you tried v3.2? The quality is much better than previous versions and I can easily watch them on a 80' screen.

[Leica]

nwg - no I have version 3.1.5. Is 3.2 much better? Regardless, there is no substitute for bit rate. How can it be? Unless of course the codec is changed from MPEG-2 to VMC9 or H.264, which for DVDs is not possible.

[bongoman31]

For clarification: I mean use Shrink, not to shrink it, but as the vehicle to make the iso file. It is common, I do it, and have seen it recommended in countless posts, to use Shrink when you are not reducing the size.
Rip to HD with Decryptor; open file(s) from HD w/Shrink, encode & create iso; burn to disk using Decryptor.

Quality is a lot better when using AEC (Adaptive Error Compensation). It helps most at high compression (50-60%). I have had a few DVD's that come out better than DVD-RB with CCE.

I know.

Using just DVD Decrypter is still better. Why use a second program when DVD Decrypter can create the ISO.

Even on the official DVD Shrink forums, DVD Decrypter is recommended.

Is an ISO image better than using shrink with nero burning ?

No - It's simply another method of "packaging" your identical DVD source material for burning...

For singler layer no is the answer. However, with double/dual layer. Nero might place the layer change in a different place to the original. A ISO created by DVD Decrypter will always have the same layer change as the original.


Nice to see you again Setarip :).

[blutach]

AFAIK, Nero will place the LB in a different place, because when it does its own Get VTS Sectors before burning, it reallocates the sectors and "packs them in". It therefore does not honour the author's intentions in respect of sector layout.

DVD Decrypter's ISO mode will honour the original LB or you can calculate something else. However, the PgcEdit method, allows you to put your LB wherever you like, which may be at a better place on the disk than the original authoring.

So, take your pick.

I did four DL burns with Nero before using DVD Decrypter. The LB was the same as the original for three and one was not.

A few comments...

Using DVD Shrink to create an ISO image after ripping in file mode allows you to strip all the preventable button presses.
Maybe there is an easier way to do it but I use this method.

I am very happy with Shrink's AEC method but if I can't get to > 80%, I just split the movie on 2 discs.

DL media is always around $4, ripping 2 $.30 DVDRs is a much better value.

What do you mean?

If you are talking about FBI skip or preventing adverts to be skipped. DVD Decrypter will do that already.

Automatically or do you have to change a setting?

I know Decryptor will strip them out in File mode, but will it strip it out in ISO read mode?

Every DVD that I backup to an ISO and then burn comes out exactly like the original with DVD Decryptor.

Yes. To be sure, check that Remove IFO PUO's is ticked in the ISO section of the settings.

Thanks! Saves me a step.

Likewise, I'm sure ;>}
