The detailed issue description

My bluray play back is choppy on audio and video play back.I have Power Dvd 8, put in Avatar it said it needed to be patched so I did. Now my Blu-ray plays choppy on sound and video.
So I tried Power DVD 10 and I get the same thing.
So I put in a Blu-ray I had just watched and it now plays choppy?
Updated my video drives and reloaded my audio drivers just to be sure. All my Blu-ray now play choppy since I tried to play Avatar on my system."
