ok this is one thing I've never done. Thought I could burn dvd's (video_ts folder) with DVD Decrypter, but I assume not?

Ive looked in the video help thread, and followed the instructions to use Nero from one of those sites, but I get an error in Nero, then it wont play on my DVD player once burnt.

Whats the easiest way to burn these DVD's?

no one can help?

DVDSanta, I hear, works well.

yep.

Just download the trial version, that's all you need for burning .isos or all the files in a typical VIDEO_TS folder.

nero .. one of the greatest programs on the face of this planet.

Burning DVD filestructure with Nero:
If you downloaded a DVD from a torrent you might get a DVD file structure instead of the ISO-Image that was described above. Generally a DVD filestructure looks like this:

AUDIO_TS (folder)
(empty)

VIDEO_TS (folder)
VIDEO_TS.BUP (Backup of xy.IFO)
VIDEO_TS.IFO (DVD Information File, like Chapter information, audio streams ...)
VIDEO_TS.VOB
VTS_01_0.BUP
VTS_01_0.IFO (Menu Information File, Navigation structure ...)
VTS_01_0.VOB (Menu Video files / Menu images)
VTS_01_1.VOB (Show Video file 1)
VTS_01_2.VOB (Show Video file 2)
...

To burn a DVD filestructure Nero is the easiest way to go. Start Nero Burning ROM and select DVD-Video from the dialog box. Press "new" and you should get 2 browser windows. On the left side you see the DVD directories AUDIO_TS and VIDEO_TS, on the right side you can browse your harddrive. To burn a disc just drag and drop all files from the downloaded directory to the VIDEO_TS directory in the DVD filestructure. After that just name the disc and follow the NERO burning dialog.

I did that for one DVD and it worked, tried another and got an error:

"DVD reallocation failed, the dvd might be unplayable"

I burned it anyway and it was unplayable.

This is for the Music Videos 1991-2006 DVD torrent from Youkan.
No idea why that wont burn the same as the other dvd i just burnt
