That can happen if the load is split bad ord if you have a to slow
network. The distributes encoding with several machines workes better
when you have only machines below 1GHz CPU frequency. (The slower the
besser ;) )
On a really fast machine that does not help much more. Sometimes the
network might become the bottleneck.

>>> I used this cmd to encode a movie:
>>>
>>> lav2yuv test.liste | yuvcorrect -Y CONFORM | y4mshift -n -4 |
>>> y4mscaler -v0 -O sar=59:54 -O size=720x576 | yuvdeinterlace |
>>> yuvmedianfilter | yuvdenoise -m 2,2,2 -g 64,255,255 -t 3,3,3 |
>>> y4munsharp | mpeg2enc -f8 -D 10 -E -10 -q 5 -b 7800 -M 2 -K tmpgenc
>>> -4 1 -2 1 -o test.m2v
>>> When it´s running i still have around 30% "free" cpu time, also when

There a 2nd buffer might help after yuvmedinafilter. It won't help if
yuvmedinafillter need 100% of one cpu and all the other programms need
together only 70% of the 2nd cpu.

Who much CPU time do all the programms use ? Could you please post a
screenshot of top when you encode the movie.


auf hoffentlich bald,
