i do have the plasma in the front of the room. and i have lots of windows. but i don't think it's interference from the plasma , sunlight , lights. what i think... it's coming from ir. signal bouncing around the room(alot of reflective surfaces). if i aim at the front of the equip. it works fine. as soon as i turn around and aim towards the plasma it freaks. i tried unhooking the ir. system and just work off it bouncing to the back of the room and it's not consistent. my equip. in cab. doesn't work at all and the equip. up above only 50% of the time give or take. i also used the sheilds and if i cover over any more of the front of the equip. i will cover up the display.
