Getting DVD +R DL To Act As A DVD-ROM?

[thejimbo]

Hello all. First post on here so take it easy

Backed up a video file onto a DVD+R DL. The burn went OK a plays on my PC and a DIVX DVD player only problem is I want it to play on my stand alone DVD player that doesn't support DVD+R DL playback. I tried setting the book type o DVD-ROM but still no joy.

After looking at a 'studio' DVD9 media disk it has a book type of DVD-ROM but the media type also comes up as DVD-ROM.

My question is this, do the 'studios' use different DVD9 disks to burn the films and get them to play on a DVD player? If so where can I purchase these disks? Or is it a burning procedure? If so what is it?

The studio DVDs are not burnt, but pressed. It's not at all the same thing, and you cannot do that without very expensive hardware.

I want it to play on my stand alone DVD player that doesn't support DVD+R DL playback.
If it doesn't support DVD+R DL playback, it just doesn't support it, any more than a cassette player can play a DVD. If it supports single-layer disks, you might look into DVD Shrink.

Hi!

Although it's VERY likely that, as suggested by "CWR03", your standalone player simply doesn't recognize burned DL media, I'd ask you two questions.

1) You state:Backed up a video file onto a DVD+R DLIs this in DVD-compliant format (.IFOs, .BUPs, and .VOBs)?

2) Are you (as you should) using Verbatim DL DVD+R burnable media?

[thejimbo]

CWR03 - I understand that. I was just going on a slight chance that I could get it to work. My hopes were raised after setting the book type but this made no difference hence asking about the difference with 'studio' DVD9 media

Setarip_old - 1) It was burnt in standard DVD format with VIDEO_TS and AUDIO_TS folders and the usual stuff in the VIDEO_TS folder.
2) I did not use the Verbatim media as wasn't too aware of how highlt popular they are, esp on this board. Not too sure this would make too much difference for my particual experiment unless you suggest otherwise

[r0lZ]

Which program did you use to burn the DVD-Video files? And in which mode?

You don't absolutely need to use Verbatim discs, as long as you use excellent media (MCC or TY.) And Verbatim is the only brand that constantly produces excellent media. If you prefer to burn some coasters before deciding that a particular brand is pure crap, feel free to try whatever you want, but don't be surprised if your standalone don't like your copies, and don't complain in the forums! ;)

[thejimbo]

I did use Nero to burn it, please don't shout. Since being here I realise that is bad news. I think that the DVD player won't play them full stop. But you never know.

Is there much success in getting DVD +R DL to work on DVD players that don't support it?

Again, if it doesn't support it, it doesn't support it. If the player simply doesn't support DL playback, it's a media compatibility issue, just like a CD player can't play a DVD.

[DaChew]

if it plays in a newer player(the divx one) and you verified it was bitsett to dvd-rom and you didn't use verbatim, then consider yourself lucky, what did you use to verify the bitsetting with?

post that nero log?

Very old (12-speed and earlier) CDRs had a surface with 5% refectivity (the standard for pressed CDs is around 30%). This was necessary so that the disks could absorb enough light from early CD writers. These disks were not always compatible with early (1980s) audio CD players.

CDRW disks were a more fundamental change. Instead of having black and silver dots to absorb or reflect light, the disks had a glass-like layer whose molecular structure could be altered by heating and cooling, to reflect or scatter laser light. This required a redesign of CD-ROM drives to enable compatibility with the new disks (coinciding roughly with the introduction of 8-speed drives.)

I have an old set-top DVD player whose manual says it can play DVD+/-R and DVD+/-RW disks; it doesn't mention DVD+R DL disks, because it predates them. It can't play 4-speed DVD+RW disks, but a firmware update would certainly fix this problem.

It took a certain flash of inspiration to realise that two layers can be read from one side of a pressed DVD, and another to work out how dual layer DVD+R disks could be written. I don't know whether the exact same method is used to read DVD+R DL and DVD-ROM disks (so all you'd need is for the manufacturer to provide a means to upgrade the firmware), or there's a fundamental difference (so you'd need a hardware redesign to support DVD+R DL disks).

I assume the announced forthcoming DVD+RW DL and DVD-RW DL disks will play on all current DVD-ROM drives, or what's the point in having them? Even then, I fail to see who would buy a new DVDRW DL writer, when HD-DVD writers are fast approaching a price at which they can become mainstream.

Is there much success in getting DVD +R DL to work...I'm surprised thejimbo that your player does not accept +R DL discs--my original player from 1997 works with mine.

It's possible you just haven't hit on exactly the right combo of burner & bitsetting & media but it could be expensive for you to find these by trial & error.

Your best bet I think is to fish around for someone who can loan you a homemade DVD+R DL that is known to work (in other players). That will tell you whether your player is to blame, or your methodology.

[thejimbo]

Well thanks for the info.

Laserfan - I have also got the disk to work in the Philips 728 which doesn't state that it supports DVD+R DL either and I think this is an older modle.

DaChew - I used DVDinfo to check the bitsetting, I think, will check later and post Nero Log.

CWR03 - I completly understand what you are saying and agree with you, BUT I can't believe it's that simple, as its a type of DVD and must be a way of getting it to work. Maybe I am just wishing.

[jshumate]

thejimbo - If you want DVD DL burns to work, you do the following:

Use ONLY Verbatim DVD+R DL discs.
Burn with ImgBurn.

Deviate from this and you post to the forum asking why your burns don't work.

Do note that DVD+/-DL discs had to do some interesting things with dyes to get them to work at all. Just a few years ago the manufacturers were saying that it was IMPOSSIBLE to create a consumer burnable DVD DL disc. There are no guarantees that such discs will work on standalone players. Mostly they seem to work, but not reliably. It's a long story I'll skip, but note that you can't find DVD+/-RW DL discs anywhere for sale, even though both the DVD+RW and DVD-RW camps announced such discs over a year ago. Taiyo Yuden doesn't make any dual layer or re-writable media either. All of this should give you an idea that getting dual layer discs to work at all was quite a feat and they don't work as reliably as single layer discs.

@thejimbo

Knowledgable posters at this and a multitude of other forums strongly advise two specific steps for likely successful burns of DL media:

1) Use "IMGBurn" for burning, rather than NERO

2) Use Verbatim DL DVD+R - and burn at 2.4X

BTW - What is the brand and model number of your burner?

setarip_old, can you plz help me?

Hi!setarip_old, can you plz help me?Help with what?

If you're seeking assistance regarding something in this thread, please state what it is.

Otherwise, create a new thread...

[thejimbo]

Setarip_old - I am using a Optiarc AD7170. I understand the knowledge behind Verbatim and ImgBurn and will try these next time. Just hoping to get more understanding on the DL issue

[setarip_old]

Just hoping to get more understanding on the DL issueWhat further understanding are you seeking?

Some factual statements regarding burnable DVD media:

1) Not all players can play both +R and -R media (Some players can play only one format or the other)

2) Not all players will play all brands of burnable media

3) Not all players can play burned D/L media

4) Virtually no playback success has been claimed by anybody regarding -R D/L burnable media

5) IMGBurn appears to be the most successful at properly determining (critical for successful playback) a good "layerbreak" location for D/L burns

6) Presently, Verbatim D/L DVD+Rs continue to be indicated as the only consistently successful burnable D/L media

7) For D/L burnable media , your Optiarc AD7170 automatically performs bitsetting (Changing booktype to "DVD-ROM")

[thejimbo]

Thanks for the info. Just to say my drive is automatically set to book type DVD-ROM. I did flash the drive and manual change it as well. Will give the method of IMGburn and Verbatim DL a go. See if I can get more positive results

[setarip_old]

By the way, setting of booktype is NOT possible with -R media (S/L or D/L), only with +R media...
