i haven't seen this addressed on here re: processor speed. i'm running a laptop with a P4-M 2.5 gig processor. however, when i check "my computer" properties, sometimes i see, under the processor speed, a different speed, such as 1.2 gigs or 500 Mhz, which i take to be the speed the laptop is running at, at that time. does anyone know why this is happening and a way to prevent it? this might be slowing down my encoding speeds (i range from 1,500k--12,000k but average maybe 3,000). thanks.
