For some it would complain that "some incompatible files were found.would you like to convert those files to DVD mpg?" Since DVD Imager crashes in SL, I switched to Burn (), but I found that it only worked for *some* DVDs, not all. How do you burn a disk with files in a certain order?įor me, DVD Imager () worked perfectly for many different DVDs until I upgraded to Snow Leopard. I’ve experimented with various disc images & software tools (e.g Burn), with no success. So the problem is to structure the files in the required order on the written disk, and not just alphabetically. HERE’S AN EXAMPLE OF A CORRECT VIDEO_TS FOLDER: In fact a DVD player doesn’t even understand files and only uses sector offsets to find data. 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. That’s why the mac can play the disk OK, but not a DVD player. 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. Unfortunately, alphabetically the file “VIDEO_TS.BUP” comes first and the mac writes this file first when burning a plain data disk. If the DVD player can’t find the IFO file or finds another file first it generally gives up. 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. 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.
