malatekid,
Thanks. That helped alot (but brought up another question). I get the same results as he did and rendering is very fast in those modes.
ggrussell,
Thanks for the reply. I apologize for not stating more information. I am running Windows XP SP3 and have no plans to upgrade to Windows 7 until they have at least SP1 released for it

My next question is: While I applaud Roxio for supporting both ATI Stream and NVidia CUDA, the support seems lacking in the extreme. I suppose that since SOME of the rendering paths support GPU rendering, it is lawful for Roxio to say that the 2010 program utilizes them, but since it is a minority of the rendering functions, it seems like quite a slant to me.
Does Roxio have any plans to release a service pack that enables more GPU rendering paths?
