A few months ago I posted about folks seeing glitching while watching live TV if they were using AMD Dual Core Processors.
There was a driver update that came out that I pointed to.
A co-worker of mine mailed and said there was a newer driver.
Hopefully if anyone still has issues here this will fix the glitching for them.
