If a couple minutes to save hours of encoding time doesn't make it

Supposedly but since the most common (that I have seen) use of the
MP4 container (aka Quicktime) is for 320x240 "web movie" sized
images I don't know if the players will have problems with large
files or not.

Welcome! Uh, mpeg4ip is a big project - useful to have though.

And neither am I. Current usage differentiates between computer
software playback and a box that sits on top of the TV. Go to any
video forum/mailinglist/whatever - you'll see that STB means standalone
unit and not a computer.

If it's clean material that's a bit on the high side. There are
options to ffmpeg/mencoder that will allow the use of a considerably
lower bitrate. Mencoder can do the cropping without a speed penalty
and that would save some bits. I've done some encoding at ~1500
which came out looking more than acceptable for casual viewing.

Yep - but most TV shows are well less than that (most movies
too except for the occasional epic length ones). Hmmm, MPlayer
can handle multiple files I believe so that would be another way to
handle the long movies - use 2 files perhaps.
