... and you have to expect operating systems where the ISO filesystem driver cannot cope with >2GB ? How about a raw 1:1 copy on DVD media then ? Like growisofs ... -Z /dev/sr0=/my/mpeg.mpg (or an according cdrecord-ProDVD command). I hesitated to propose this. But nobody came up with a better idea and mine is at least simple. Since i myself did not experience read-ahead bugs with DVD this would work for me without padding. If needed, one could add about 300 kB (or 1 MB, according to Volker) to the mpeg file on disk or one could add it on the fly. Like (dd if=/my/mpeg.mpg ; dd if=/dev/zero bs=2K count=150 ) | \ growisofs ... -Z /dev/sr0=/proc/self/fd/0 If you are still using scdbackup, the following might be the most convenient method (presuming version 0.8.4): dd if=/my/mpeg.mpg | sdvdbackup -pipe_to_media (This provides blanking, padding and checksum tag.) It remains to be tested wether mplayer/xine will accept /dev/dvd as input. Of course there may arise a problem with the fact that raw streams from DVD may be much longer than the data which have been written to DVD. (Does MPEG2 recognize the end of file from the data content ?) For me MPlayer started to play a movie from /dev/sr0 (and issued a misleading error message when there was no r-permission for my video-sandbox user). The movie (12 MB) froze rather than ending when it was done. Probably MPLayer was reading 4 GB of trash from the DVD+RW media and would have ended afterwards. If playing the movie from disk filesystem, MPlayer ends with "Exiting... (End of file)". So the movie file might be incomplete.
