DL question - VOBU/ECC

[geohei]

Hi.

 

I created an image for a DL DVD+R using Adobe Encore DVD (2.0). When I burn the DVD using Encore, it's unreadable (for some reason). I was told to avoid Nero and use ImgBurn instead.

 

Are the default ImgBurn settings the best choice?

 

By mistake, I burned a DVD using this feature (out of the log):

...

W 18:15:54 User has ignored layer break options and instead reverted to VOBU/ECC search!

I 18:15:54 Optimal L0 Data Zone Capacity: 2.065.152

I 18:15:54 Optimal L0 Data Zone Method: ECC Block Boundary, VOBU Boundary

...

- What does this mean?

- Do I have to expect problems with this DVD?

 

Thanks,

 

... later ...

 

The verify for this DVD failed

If you have winrar installed extract the ISO encore created and then switch to build mode in ImgBurn and feed it the extracted encore ISO/ which has become VIDEO_TS and select a laybreak that way then burn.

If you don't have WinRAR, use this free program instead.

Also post a log of the failed attempt

I don't have to create an img file. I can also instruct Encore to create a VIDEO_TS folder including the .vob/.ifo/.bup files (makes the use of WinRAR obsolete). Is this preferential to the .img file when it comes to burning the stuff using ImgBurn?

 

What about the VOBU/ECC question? Nobody knows? (and the other questions ...)

 

2 DL DVDs failed now. It starts to become expensive! The first DVD failed at the very end, the second in the middle.

Yes it's better to feed ImgBurn the IFO/VOB/BUP files.

 

That way it has more control over the alignment of Cells when it comes to making a decent layer break point.

 

You ignoring the nicely aligned cell / layer break options has nothing to do with why the verify failed. It failed because your drive produced a bad burn on that media. That happens a lot when you use the cheapo double layer discs and it's why we recommend people buy the Verbatim ones instead. They cost more because they actually work!

 

ECC/VOBU is the fallback method for burning DL content. It breaks the DVD Video specs because they say that the layer break should no occur in the middle of a cell. Some players will just give up at the LB point if that's the case, others will play on regardless. Splitting it properly at a cell will give you a more compatible disc.
