[mythtv] transcoding with cutlist

Or you could just not use a fifo/pipe for the audio.  My svcd encoder
just write the audio to a file while it encodes the video that mplayer
puts into a fifo for me (I use mplayer to decode nuv to yuv, rather than
doing a stream copy into an avi).  Then again, 600 megs or so of audio
data sitting on my drive for an hour or two while the video encodes
isn't a big deal to me.

Unfortunately, it seems that mplayer can't get the audio sync'd right on
any of my nuv files, so I have to wait for someone to update the patch.
