I think I was interested in how mplayer resamples because I thought
resampling was necessary to combine the 6 channels into 2. Now that
you've told me resampling isn't necessary in order to downmix, I guess
I don't need to worry about it. My sound card handles 16/24 44.1, 48,
88.2, and 96. mplayer should never resample a DVD or Blu-Ray I play,
correct?

I didn't realize that, thank you.
