I have a Philips DSX5600 receiver with the remote which will control SAT/TV/VCR/DVD. The problem is that it just stopped working for the SAT controls! It still works perfectly to control TV, VCR, etc, but not the SAT (which is obviously the most important!) When I press the SAT button, it lights, but then ignores every other button pressed (normally the SAT button blinks whenever another button is pressed) until I select a different device.

Does anyone have any clue why this would happen?
