The reason a DVD player is unable to recognise the disk is that it requires the files in the VIDEO_TS to be physically in the correct order, in particular the VIDEO_TS.IFO file should come first. When you insert a disk into a DVD player it scans the first few sectors looking for this file which contains a list of sector offsets to find the title sets on the DVD. If the DVD player can’t find the IFO file or finds another file first it generally gives up.

Unfortunately, alphabetically the file “VIDEO_TS.BUP” comes first and the mac writes this file first when burning a plain data disk. A computer DVD player, on the other hand, understands the file system on the disk and can therefore find any file it wants with out having to know the offset values. That’s why the mac can play the disk OK, but not a DVD player.

It is also important that the VOB files are in the correct order as a DVD player just plays the data it finds, ignoring file boundaries, until it reaches the end. In fact a DVD player doesn’t even understand files and only uses sector offsets to find data.

HERE’S AN EXAMPLE OF A CORRECT VIDEO_TS FOLDER:

VIDEO_TS.IFO
VIDEO_TS.VOB
VIDEO_TS.BUP
VTS_01_0.IFO
VTS_01_0.VOB
VTS_01_1.VOB
VTS_01_2.VOB
VTS_01_0.BUP
VTS_02_0.IFO
VTS_02_0.VOB
VTS_02_1.VOB
VTS_02_0.BUP

So the problem is to structure the files in the required order on the written disk, and not just alphabetically. I’ve experimented with various disc images & software tools (e.g Burn), with no success. How do you burn a disk with files in a certain order?

Any suggestions?
