Convertxtodvd 3.3 problem

Hello all

I have a:

Toshiba Satellite A305D-S6848 laptop.
AMD Turion 64 X2 Mobile Technology TL-60 2.00 GHZ
3 GB Ram
Microsoft Windows Vista Home Premium 32 Bit

My favorite program to encode divx/xvid to DVD is Convertxtodvd. I’ve used it for almost a year now. And recently, everytime I get anywhere fomr 20% to 50% of the encode, I get a BSoD (blue screen of death) with the error sayin something about video scheduler error. Almost everytime I run it I get this error. I’ve updated all drivers for video card and bios. I’ve upgraded to the most recent version of Convertxtodvd. Anyone can help please that would be awesome!
