I'm having difficulties syncing a variety of audio sources with the GOUT. Below is a list of times for vaarious audio sources as well as the length of the movies themselves. None of the timings are the same. Obvious the GOUT audio syncs up with the GOUT video, but I have no clue how to make the other sources sync up. When I mux these various audio sources with the video, it's always out of sync. Help and advice would be most appreciated.

Ep IV - ANH 2h01m00.22s
2006 GOUT DVD - 2h01m07.424s
1977 Restored Mono - 2h01m07.328s (Audio for GOUT projects - "77_sw_restored_mono_mix.par2")
1977 35mm Dolby Stereo (Reference Level) - 2h01m10.016s (Audio for GOUT projects - "77_ss_dolby_stereo_reference_level_belbucus.par2")
