You can play around with scheduling priorities some using nice (assuming
linux or some other POSIXy operating system).

If you're *really* feeling adventurous (i.e. reckless) download and build:

http://www.eastcheap.org/tarballs/antinice-1.1.3.tar.gz

which will allow you run mencoder (or anything else) with absolute
priorities greater than 0 (round-robin priority 1 is sufficient to trump
most other processes). It might help, it might make things worse...heck,
depending on the options you feed it (and how the kernel is configured),
it might lock up your system entirely.
