About the speed issues which were reported by tormento:
I tried to replicate the issues under a 32-bit environment, and I couldn't. The script speeds reported by AvsMeter were always identical, and measuring the speeds for a real conversion using X264 was also uneventful. I always got the same speed with AVS+ 3.40 and AVS+ r2915, no matter how simple or complex my script was.
Could this issue be a 64-bit thing?
Cheers
