As I wrote in the mail shortly before you should not use the -M switch (or any other spliting by mplex). If you multiplex a DVD the -M switch was deactivated because it generated several files. The -M option does not generate valid MPEG streams. You should use the -S -B option of mpeg2enc for spliting videos. > Pretty neat that I can burn MPEG-2 video to a DVD, and that it works in > my player; as far as I can tell, that's not "standard", i.e. I think > the audio is supposed to be uncompressed 48kHz PCM.
