Can't use the tuner or anything like that (yet), and at $199 list
it's not cheap, but it will give you an MPEG-2 stream / file, and it
won't use a lot of CPU to encode.

Isaac, is there anything in mythtv that currently locks in nupple /
mpeg4? I'm assuming that if libavcodec is able to decode it, then
(somehow) the data could get displayed. Do I have that thinking
right?

Thanks, Bob

Is there anything preventing MythTV from using MPEG2 codec? There's an
encoder/decoder over on SourceForge I believe. It's a bit old, but it
does work. A friend of mine is using it right now.

How fast is it? The mpeg2 encoders I've tried have been far too slow to do
encoding in real time on my dual 500MHz Celeron box, far slower than mpeg4
encoding.

Here's the link. It seems to be pretty fast, Freevo uses this lib I
think.
http://libmpeg2.sourceforge.net

Here you go!

Freevo doesn't -- it just calls mplayer for everything.

This is a decoder, not an encoder. Did you mean mpeg2enc from the mjpeg-tools
package?
