As commentary section says the patch should improve compatibility with consumer DVD-Video players by sorting file entries in VIDEO_TS directory in the same order as the files those entries point to are laid down on the disk: 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 .... In comparison to the current outcome which is VIDEO_TS.BUP VIDEO_TS.IFO VIDEO_TS.VOB VTS_01_0.BUP VTS_01_0.IFO VTS_01_0.VOB VTS_01_1.VOB VTS_01_2.VOB ... In general how do consumer players work? To play the whole video content it's actually sufficient to locate a single file (and most players do just that), VIDEO_TS.IFO to be specific, which contains references to all titlesets. The catch is that those references are *relative* to first LBA of VIDEO_TS.IFO. If player is stupid enough to assume first file to be VIDEO_TS.IFO it will end up with VIDEO_TS.BUP's first LBA instead. Now given that VIDEO_TS.BUP is verbatim copy of VIDEO_TS.IFO attempt to dereference those relative pointers will effectively result in garbled playback. > Your patch is for Joliet and DVD video while a Video DVD should not > include Joliet.... See line#2869 in mkisofs.c. UDF uses Joliet's directory sorting procedure, which is why joliet.c gets patched. Cheers.
