How to help Vegas 8.0c or WMV use more CPU cores

I think I just stumbled on something...

Got three Vegas (8.0c) processes on the go, all rendering (to WMV) at the same time. Wondered why, according to Task Manager, nearly all the load was on CPU0, the other 7 just trickling along. So in Task Manager > Processes, for each "vegas80.exe" process in turn, did RightClick > Set Affinity. Left the first process alone then removed CPU0 from the second "vegas80.exe" process and CPU0 and CPU1 from the other.

Result: Total CPU load is now doubled (and all 8 cores are sharing pretty equally).

Duh !

Who knows if that's a Vegas 8.0c or a WMV issue. Wonder if Vegas 9 does any different (I won't install it until my main project is finished).

Don't know the answer to your question right off, but in Vista/7 most encoders use all cores, where the same apps in XP usually just show 1. Vegas 9 for me works 4 cores in XP or Vista/7 going to mpg2. Wmv itself has issues, with quite a bit written about it on-line over the years. If you want to see if 9 makes a difference, back up your system & install the trial.
