That's odd. Offhand, I would expect 50-70fps xvid encoding of a 
normal-resolution movie on a 3000+.

Have you checked to make sure your Athlon64 machine is working properly? 
For example, I use ondemand CPU frequency scaling and sometimes it gets 
stuck at the lowest frequency. If nothing is readily apparent, try some 
unrelated CPU benchmark like:
$ time bzip2 some_file -c > /dev/null

Is your hard disk working properly? Check DMA:
# hdparm -d /dev/sda
(replace sda with whatever disk you're using)
...or run a quick test:
# hdparm -t /dev/sda

Are you using a recent enough xvid? What compiler are you using?

By the way, using frameno never worked quite right and it's now 
deprecated. I doubt that is related to your speed problem.
