Render speed changes about 43% in

Now this is interesting, figure this one out
I am rendering a MPEG 2 to a MPEG 4. When the render starts the frames in the preview window are speeding by, quite impressive. Both processing cores are at 98%. Then about 43% into the render the rendering will start to slow down. The resource monitor shows core 1 still at about 98% usage, but core 2 is decreasing down to about 50%. The frames aren’t speeding by anymore and the render time starts to triple. The processors will stay like this until the video render is finished, much later than expected. It happens every time. Each video is only about 4mins.
I have tried changing the priority and the affinity in the task manager for Vegas. I have turned off my Avast virus scanner. Is the hard drive bogging down? The hard drive light doesn’t show signs of stress. Memory stays at about 1.8 gigabytes free.
No major programs running in the background.
I will see if this problem occurs with other formats.
I am running a HP Toshiba dv6815nr
AMD Turion64 x2 2.0 ghz
3 megs of ram
plenty of hard drive space
Windows Vista Home Premium 32bit sp1
Vegas Video 8.0a
Thanks for any advice. You guys are great around here

To my recollection that is how vegas functions when rendering mpg4 file formats. Did the final render had any errors?
I would also recommend you upgrade to version 8.0b
