Hmm, I was under the impression that the currently available
'uncompressed' option would leave all the channels present in the
audio. I did the simple 'ear' test by playing an hd show after I
transcoded to MPEG4 and had what sounded like surround channels coming
through my rear speakers. This was limited to about 5 seconds. After
that I started transcoding all my hd material like mad. Heh, oops.
Guess I should have been a little more thorough in my testing.
