I’ve never used Intel

I’ve never used Intel graphics for my HTPC but I had the same issue about 2years ago using an ATI 5450 card.  The issue as I understand it is an incompatability between the MPG encoder the network is using and the MS decoder. When the frame rate would change the brightness level would flash.  It was only on a few channels and only with a few programs. The solution for me was to upgrade my graphics card.  An Nvidia 430GT worked but it’s SD performance was terrible. I am currently using an AMD A4 w/ 6450 graphics in it and there are no flashing issues. Good luck. Let us know how it goes.
