I don't think Xvid is multithreaded

Nice

threads: This option allows to spawn threads to encode in parallel on
multiple CPUs. You can manually select the number of threads to be created
or, better, set threads=auto and let x264 detect how many CPUs are available
and pick an appropriate number of threads. If you have a multi-processor
machine, you should really consider using it as it can to increase encoding
speed linearly with the number of CPU cores (about 94% per CPU core), with
very little quality reduction (about 0.005dB for dual processor, about
0.01dB for a quad processor machine).

I will be giving it a try, anyone have experience with this and dual core
cpus?
