Capping Issues

So very very frustrating but I'm hoping the good people of here can help me :)

I had Power DVD 4 which I had no problems capping from. I recently upgraded to Power DVD 5 which has required me to take down my hardware acceleration, something 4 never needed. My caps are coming out rather badly :(

Can anyone tell me if version 6 has the requirement? Or possibly tell me how to improve my capping quality?

Thanks!
