Perhaps with the CVS version that is the case, but historically, I have
not been able to get more than 5fps with mpec2enc whereas libavcodec
gives me closer to 20fps.

Yeah, both dealing with avi and trying to not have to deal with it. 
What a bag of crap avi is.

Indeed.  The difference is only just becoming clear with this thread.  I
now understand that I want the MPEG stream that would be in the
container that mencoders -of mpeg spit's out.  I might take a look at
the demuxing tool you mentioned in the other message in this thread.

Yes, indeed.  Until the last few hours, the difference between an
MPEG-ES and an MPEG-PS was unclear.

Perhaps mpeg2enc has gotten _a_lot_ more efficient recently, but
historically, the best I have seen out of mpeg2enc on my hardware is
<5fps.

Yes, using DirectFB on a Matrox G400 with it's excellent CRTC2 support.

Which is what I am using currently, but so far, the only containers I
have been able to put that into is avi and ogm, as far as mplayer
playing from either of those, it sucks rocks.

OK.

What exactly is your distinction here?  A set-top box is a computer. 
Perhaps your distinction is between hardware and software decoding?

My impressions have always been that for interlaced television output,
MPEG2 is the best.

And other than having to use either an avi or ogm container, I would
continue to be happy with it.  But both avi and ogm has issues (at least
where mplayer is concerned) with files >2G.
