If you're not running a 64-bit kernel, you won't be able to use 32-bit 
programs anyway. Running 32-bit code on an amd64 system shouldn't give 
you that much of a slowdown.

I don't have a current 32-bit mplayer build, so here are results from 
both 32-bit and 64-bit versions of MEncoder dev-CVS-060309-12:34-4.0.3

32-bit lavc

real    0m24.973s
user    0m23.806s
sys     0m0.319s

64-bit lavc

real    0m23.339s
user    0m22.645s
sys     0m0.253s

32-bit xvid

real    1m11.098s
user    1m10.074s
sys     0m0.526s

64-bit xvid

real    1m5.751s
user    1m3.578s
sys     0m0.526s


So, anyway, unless someone here spots what's going on, I guess your 
options are:
- ask the xvid people
- use lavc or x264 instead
- upgrade to a 64-bit system, try a different distro, etc.

Beyond that, I probably can't help you much further.
