Tried the tutorial over at Cow (http://www.zapdigital.com/v4.htm) and had all kinds of stability problems. Had crashes; de-installed & then re-installed twice. The images were ok with only PlugInPac. But Motion Blur made things worse... herky-jerky images that bogged down and stopped then tried to catch up to the cursor. Video Supersampling really bogged things down to the point were Vegas just shut down.
Set the RAM at 0 then tried it at maximum (leaving 85MB for system).

Anyone else tried this tutorial yet?

My system is:
Dual Athlon 2000+
1GB DDR
