Remember - one of those cpus is being used by yuvdenoise...
The parallelism in mpeg2enc is fairly coarse too so using 2 cpus does
not translate exactly into 2x the encoding rate.
Then too even cheap systems today (Athlon-XP3000) have more cpu power
in a single cpu than the dual P3s of yesterday.

That might help a little - newer compiler could generate better code
but I think any improvement is going to be in the few percent range
and not suddenly bring about 10 frames/sec.
If you have the diskspace you could denoise to a file and then run
mpeg2enc - that way they wouldn't be competing for the cpus. Might
speed things up at the cost of some temp space.
Good Luck.
