The other day I was watching the NFL netowork in HD in my game room on my plasma. The signal kept pikelating and having audio dropouts, so I switched over to the SD version and all was well. I didnt know what was happening but it was not doing this on my hr20 in the living room. I didnt really think about it too much. So tonight I am back in the gameroom and watching the nfl netowork in HD again. I am using the h10 HD receiver in the gameroom. I have the same channel on for at least 1 hour with no problems. It starts getting dark so I turn on some recessed theater lights with a dimmer switch on. Within 30 secs I start getting the audio dropouts and pixelated picture. On a whim, I just say...... hmmmm what the hell, is this a coincidence? I turn the lights off and picture stops having any problems. I turn the lights back on and immediately start having the same problem. Lights back off and no problems. I turn on a different light attached to my ceiling fan and no problems. With 100% certainty my damn lights in my game room are having some kind of interefernce with this HD receiver. What the hell??????? Anyone ever hear of this??
