[mythtv-users] Audio in dvd rips

[Ryan Steffes]

This is just something confusing me that problem indicates I'm not sure how 
it really works. I'm in the process of ripping all my vhs and dvds so I can 
store them away and just use the ripped version. I'm trying to preserve the 
AC3 sound for playback over my newly working (and at the time of this 
writing, one of the ONLY parts of my system working) digital sound. What's 
getting me is I'm ripping a dvd and dumping the audio track as is, and the 
file command reports:

file frameno.avi:
frameno.avi: ATSC A/52 aka AC-3 aka Dolby Digital stream, 48 kHz,, complete 
main (CM) 3 front/2 rear, LFE on,, 384 kbit/s reserved Dolby Surround mode

but once I encode the video to go with it, file reports stereo sound:
file Golden_Eye_Bond.avi:
dvd_vobs/GOLDEYEX1-1.avi: RIFF (little-endian) data, AVI, 720 x 480, ~30 
fps, video: XviD, audio: Dolby AC3 (stereo, 48000 Hz)

I do have other avi's that report as
RIFF (little-endian) data, AVI, 720 x 304, 25.00 fps, video: XviD, audio: 
Dolby AC3 (5 channels, 48000 Hz)

So it's just bugging me. I don't want to rip all my dvd's wrong, and then 
have to go back and rip the sound different to have it sound right through 
the stereo. Any one know what's going on with that?
