I had my 42" plasma horribly interfere with a StreamZap remote. The
only way I could get any consistency was to move it 3 feet to the side
of the TV (not an option). I did various tests with the receiver here,
there, tv off etc. It was clearly the tv that was causing the issue.
I wound up changing to a MCE remote and haven't had any problems since.
