I've had a breakthrough.  It turns out that if you extract streams using
mfs_ftp, you get junk every 512Mb in the stream.  (Don't know why,
something to do with how it's stored on tivo's harddrive.)  If you
extract using a program called vstream, then the junk is removed for
you.  In finding all this info, I also found the tivo-mplayer project.
They've patched MPlayer to read streams from vstream.  I've updated the
patch for current CVS and will post it now in a new thread.
