I am troubleshooting a problem I'm having where my Plasma TV (Gateway 46) is interrupting IR signals to my Sony Megachanger DVD. I have several other components that are not affected, including a Sony CD Megachanger. When I shut off the TV, the IR works fine. This problem exists with, or without, my IR repeater system (receiver, connecting block, emitter) - thus it is an issue of my Megachanger. I can't really move the DVD any further away from the TV (it is about 5 feet away). Has anyone encountered a problem like this, and what are some remedies? Can I shield my electronics cabinet to decrease the interference? Thanks in advance -this is really aggravating.
