no. you’re better off having too many checked than not enough. at least that way you knoe the one you need will be on the disk and you can use the audio button to get to it if you have to.
There’s no such thing as “compression reauthor mode”
there is however the reauthor mode in shrink. if you’re not using reauthor mode, don’t worry about it.
as far as sound cutting out part way through the movie, that should have nothing to do with the audio tracks you’ve selected. If it was there for the beginning of the movie, it should be there for the rest of the movie.
i take it the original doesn’t also carry this same problem?
i can’t think of any reason that would happen in decrypter or shrink, and I have no idea what “Deep Burner” is or how it works so I can’t speak for that.
I don’t really have much info in regards to your problem, I just wanted to clear up the above points so you don’t get more confused!
