[mythtv-users] transcoding perfect dvd rips to xvid

[Mike Schiller]

Thanks, David.  I'm definitely open to non-ffmpeg solutions, I guess I
shouldn't have been so restrictive in my posting.  Your mencoder
solution look like an excellent solution to my problem.  I do have a
couple of quick follow-up questions:

I take it that I just replace dvd://2 with the input file name?

Since it can handle anything mplayer can play, then is it safe to
assume that it will automatically handle the number of input audio
channels properly?

Does encoding the audio to MP3 preserve the number of input audio channels?

Thanks again,
Mike
