    Michael,

    I removed CCC 11.8 and installed 11.9, no joy.  I removed CCC 11.9 and installed 11.2, still no joy.  For both changes I uninstalled CCC and uninstalled the driver from device manager and started over w/ no “quality” driver installed.  Also, once the ATI driver was installed, I did a re-calibration w/ the video calibration files to set the black, white clipping and color clipping levels. 

    I didn’t read your post until I did all the driver changes, but once I was on 11.2 I checked the frame rate. The frame rate is occasionally, and very briefly, changing from 59.9401 to 29.97.  The brightness flashes seemed to be occurring at the same time as the frame rate changes.  Is this coming from the network as part of the video signal?  Is it improper deinterlacing?  Or is it a hardware issue that I will just have to live with?? 

    Also one other thing I noticed while installing various CCC versions and setting up the display again, I could not obtain correct pixel mapping unless the pixel format was set to RGB 4:4:4.  I don’t know if that might have something to do with it, but it was peculiar that the pixel format needed to be RGB on my TV (it’s a cheap Insignia from Big Box).

    Update:  I checked the frame rate on the bedroom HTPC and it also changes from 59 to 29 but no flashing brightness.  The bedroom TV is an LG.  Could it be the cheaper TV in the living room that is the issue??
