When playing on a PC the title sequence audio appears to play fine. Main movie audio is delayed by 8:46 of silence, at which point the audio starts playing from the beginning of the main movie.

File does not play on the iriver clix gen 2. Every couple releases DVDFab seems to get broken and is unable to produce valid files for this device. About 2 or 3 releases back it was fine.

Single-pass is perfectly in sync when played on a PC. Does not play on clix device.
