Wow -- didn't think the profile would cause this but I switched from
High Quality to Slim and the freezing is gone for the most part.
Quality, especially in HD didn't seem to be affected, although the guide
seemed to hesitate a little bit more in HD.  

Is this due to the on-board graphics or would this be expected results?
