Part of that is that ffmpeg/mencoder can do the conversion internally
rather than having external programs and pipes to get the 420 needed
by the encoder.

There are several demuxing tools around - pick the one that works
the easiest for you.

Ah, ok - that was what I thought might be the case.

I put the stuff into MP4 containers with AAC audio and MPEG4 video.
Not only useable with mplayer but ALSO with Apple's Quicktime player.
The couple things you'll need are the AAC encoder ("faac" from
www.audiocoding.com I believe) and 'mp4creator' (a small part of
the rather large MPEG4IP project).

No, a set-top box is the DVD player that John Q. Public gets at
Best Buy or Fry's or whatever. A computer is not considered a STB.

I thought ffmpeg's mpeg4 encoding was interlaced aware.

With mpeg4 though you can cut the bitrate down considerably below
what mpeg2 requires. ~2000 kbits/sec is more than enough for general
mpeg4 use and that's a _long_ movie at 2GB
