Actually, a lot of the confusion started here:
resulting file has masked the actual movie when using AVS Video Cnverter (like I always do) main movie is replaced with previews and commentary for other movies
The first few replies to this post didn't quite "catch on" that he was
not referring to an issue of "audio stream selection" - but rather AVS was deciding "on it's own" what to flag as the "movie" and was getting that part
wrong. Therefore, a lot of the first few posts were in reply to a problem that was other than what he was describing. (Now, had he started his
own thread, with a logfile, as prescribed by board policy - this would have likely been avoided)
We don't know why AVS is getting it wrong when Handbrake (with the setting mod), CloneDVD, PowerDVD and even DVDShrink are getting it right. Nor do we need have any further concern about it. Ample work-arounds were presented.
I'll further note that anytime I (rarely) convert a movie to another format. I always first rip the Main Movie
out of the AnyDVD rip with Shrink (with no compression) and while I'm there I uncheck everything but the 5.1 audio stream. (Same can be done with CloneDVD) Then I usually force that 5.1 stream with Shrink for an extra measure.
This is a super fast step, as no conversion or compression processing is used. You get the pure, unadulterated movie only. (saving space too!)
Then, that resulting product can be converted (with or without extra compression) using almost any conversion tool known to man. The conversion software only has to convert now - all the other decisions were already made for it.
