I've had good luck with divx. I use mencoder and the divx
encoder. I recode my stuff at a brate of 1200. It works out pretty well
for TV shows and reasonably well for movies. This is strictly for the
2nd tier movies and TV shows. I would never do divx conversions for
anything I have the slightest interest in getting in HD.
I shrink MPEG2 down to 25% of the original size.
I have to do some finagle to get xine to display the converted
avi's right but it's only a minor nuissnace. I would like to crop the
bars out of my letterboxed stuff but I haven't figure that out yet. I
can't reset the aspect ratio with the divx encoder and I dont want to
use the lavc one.
I tried h.264 but the playback speed was not good enough for
random seeking. I ended up with some freaky slow motion transform
effects going on.

Oddly enough, I've found that I like the closed captions better
as subtitles (due to be extracted from the vobs into a subtitle file to
be used with the avi).
