Im not sure how to describe this, but I ran through the codec guide from this site following all the install and settings steps perfectly, now all videos I have play which is great (mixed formats) but with everything I play through MP or even external players have this weird kind of jump line across the screen when things move quickly on the screen, kinda like the top half of the screen has moved to the next frame leaving the bottom half behind, but only for a quick second. Only really bright and fast movement scenes this is more obvious and looks like its occurring multiple times on the screen. Only in the location where the fast movement is so its not an lcd problem (internal tv works fine)

Could this be a processor/RAM issue? Perhaps a video driver? Note that im using the default drivers that vista gave me as when I tried to upgrade to the latest drivers for nvidia the screen went black and I had to reboot, after reboot I had no video drivers at all, had to then get vista to redetect and install the nvidia drivers it has itself.

I was told that I should be able to play non HD video without a problem with a 1.8GHz single core cpu, 6600GT card and 1.5G ddr400, was I told wrong?

If I try to play any 720p stuff the video will freak out an stop with my cpu going through the roof.

In Vista you should enable AERO and in configuration of MP select EVR as renderer. (in exptert mode) From what I have heard about vista, this gives the best results with image tearing/stuttering, etc.
Its always better to use the NVidia drivers of your 6600gt. (Microsoft isnt interested in optimizing for best performance, NVidia is. Default drivers will just work. Nothing more.)

1.8Ghz should be sufficient I think for SD.
I don't own a NVidia card, but maybe someone can tell you if a 6600GT can give you hardware accelerated video support. (CUDA / DXVA) If so, this will be a good way of playing Full HD material.

Thankyou, all fixed now, i did as you suggested but still had issues, it came down to the drivers. i went back about 3 versions of my video card drivers and they installed correctly, this made video playback much smoother, thanks.
