right, i understand that gknot is merely a front end for a number of other individual programs, however, it does contain an internal routine all its own that acts as a batch file to get all the progs to do their thing without any input from you. once the vobs are decrypted and a d2s file is created that is. i guess really what would be acceptable short of the massive port that you speak of, would be at least to have a prog like dvdecrypter ported. dvd roms on a pc are less tolerant of read errors than the drives on a xbox. not that the readers are any different, theyre essentially not, but the bios of the box will just read anything, crunching up errors sort of like the software "blindwrite" will do. this is because of the way the drive is told to interpret data: if you are missing a bit in a video or audio file, its not really a big deal, the drive presses on, if you are missing a bit in a data file though, you have a corrupt unusable file. since xbox wasnt really designed to run programs, but rather video (games are just videos with an argument data cruncher determining teir output) it will ignore or at least provide a greater lattitude for random read errors than would a pc. and face it, read errors are common enough trying to rip a dvd on a pc so as to be annoying. i have had many dvds that the pc couldnt rip that the xbox tore right through. the problem is, the xbox cant decrypt. So, in summary

port something to the xbox that can decrypt. <
