indeed.

geoffrey is looking after some of this i think. although, transcoding
to non-nuv isn't going to be in mythtranscode any time soon, that will
require something like mythmkmovie i think. although, it would be nice
to try and integrate mencoder a little more transparently, and michael
and i have discussed this briefly.

i think you should be able to do this now, with the enhancements that
michael submitted. if you stick to raw only (no re-encoding) i think
you will not run into any of the audio bugs in the re-encode part, and
the cutlists should be supported fine. just run mythtranscode with the
correct options and go. it will produce a XXX.nuv.tmp file that you can
use. my fixes coming next week will mainly be dealing with the
re-encoding portions, and i'm going to try and get it so that i can
convert the video from mpeg2 to mpeg4 but leave the audio as layer2.
we'll see if i can finish that in time. layer2 mightn't be as good as
layer3 stuff, but i'm sure its better to simply copy the layer2 rather
than decode it and re-encode at layer3.
getting there!
