Do you have the Viera link turned on? That's the only thing I can think of that's different then my 42" Panasonic plasma that doesn't have any Uverse remote control problems. Plenty of LCDs have had remote problems and there are a number of settings that can help them, but your's is the first plasma that I've read about remote problems.
Mine's the generation right before they came out with Viera link... but there are some "control by HDMI" options... I will try to turn them off. -- PRescott7-2097
