Difference between burning a DVD as ...

[LiorRon]

Hi,

I have already ripped the DVD with DVD Shrink and the VOB files
are inside VIDEO_TS folder on my hard drive.

My question is:
Is there a difference between burning a DVD as a DATA DVD and creating the VIDEO_TS folder vs. choosing the DVD Video project
in Nero and dropping the VOB file in there ?

Thanks

Yes. DVD Data will preserve your Video_TS folder as a sereis of files, but it won't be playable in most DVD players as they will see it as just a set of files, not a DVD. Using DVD Video you get the correct file structure and it will be recognised as a DVD Video, not a plain data disk.

Can I suggest that if you are using DVD Shrink you also install DVD Decrypter, and when you backup using Shrink, choose the Create ISO and Burn with DVD Decryper option. Then you don't have to worry about these matters.

I'm sure you can select DVD (UDF/ISO), drag the VIDEO_TS and AUDIO_TS folders onto the disc and it'll still be a "compliant" DVD. Either that or there's a shitload of guides in the guides section that are F.O.S.

Is UDF the only allowable filesystem for DVD ?

UDF or UDF/ISO bridge, yes

Thanks for the replies.
I would like to temporarily rip the DVD to my hard drive and watch from my hard drive, and if I decide
I like it I will burn it. From the replies above the best solution is ripping it as an ISO. After I have the ISO on my hard drive is it possible to play it ?
Is there any tool ?

Yep, mount the image with daemon tools (adware - but you can choose not ot install the 'ad' bit) or nero imgdrive (payware). This will create a virtual CD/DVD drive for you to use your favourite playing software.

Can you expand more on how specifically the file structure will differ between saving as a data DVD vs DVD video? I use Roxio Easy CD creator 5 and do most of mine ad data DVDs (I believe the only option in this version). My player plays them fine. But copies I have made for others have given other people trouble. I never realized this. And I would like to know more about the specifics.

Now, THAT'S a good question...

The DVD-Video application format is a Data Disc, but with particular constraints:

1. Filesystem must be (micro)UDF v1.02 (which may be bridged with ISO9660)
2. Files must be contiguous (no breaks/fragmenting)
3. Files must be recorded in a particular order (VIDEO_TS.IFO 1st, etc)
4. Files (in VIDEO_TS or AUDIO_TS) must ALL be less than 1GB
5. Files must have no "Default Operating System Designator"
6. Only certain files are allowed in the VIDEO_TS folder (authored files)
7. The VIDEO_TS folder, AUDIO_TS folder, and any contained files must have set the "High Priority flag" ( IIRC ? )
8. Disc should be recorded single track, single session
9. Disc must fill at least 1GB (if data isn't that long, extend the leadout)
...there may be other requirements.

Standard Data DVD discs can be created that don't follow all those requirements and still work fine as data discs, but then that loses compliancy/compatibility for DVD-Video.
You could create a standard data disc and add the files and IF your burning application could precisely control for all those requirements, then you would be making a DVD-Video compliant data disc. But it's just so much easier to use an app that specifically supports the DVD-Video spec.

BSPlayer will play the VOB file directly...

Follow up question. And thanks for the info by the way.

Let's say you have a disc and want to determine whether it is truely compliant. What would be a good way to do it? What applications would be usefull?

[Cornucopia]

The corporate/business way to do it:

Get a copy of DVD-Video verifying software (from Philips, Eclipse and others). Cost=$$$$. There was a thread about this just the other day.
They'll let you know if all your ducks are in a row.

The prosumer/anecdotal/experiential way to do it:

Use ISOBuster to veryify session/track info and sector-by-sector file order. There are other softwares that can tell you UDF v.#, etc. But the best way to tell is by getting some REALLY PICKY settop players (esp. older ones) and trying them in there. If they play correctly there, it's compliant enough!
