I hope this isn't a well-known issue that I've somehow missed, but ....

My 970 no longer responds to any commands from the remote control. The remote's buttons still light up, and I did try inserting brand-new batteries, but still nothing.

The 970 does respond to commands from a universal remote (Logitech) that I've programmed for it, so it hasn't gone deaf, it just seems that the remote is no longer talking or it's speaking the wrong language.

Any ideas?
