Since the CPU is slow, you had better restrict yourself
to "light" compression, i.e. mpeg1 or possibly mpeg2,
but definitely not any of the mpeg4 variants, which are
much more cpu-intensive. The resultant file will be 
somewaht bigger, but will be created faster ...

Better yet, _if_ you have disk space, why not capture
your TV programs without encoding (using mplayer -dumpstream)
and encode later. This way is best, because mplayer -dumpstream
doesn't consume much cpu, and for the later encoding pass 
you can use the best options, you have all the time you want.
