Yamaha RX-V1300 receiver problem

I've had a Yamaha RX-V1300 receiver for six years without encountering any problems. Last night I switched the setting from CBSAT to DVD and listended to a CD before turning in. This afternoon, I switched the setting by remote from DVD to CBSAT. The change showed on the remote, but did not change on the receiver. I then manually switched the receiver. While it changed on the receiver's face, the actual setting did not change and I'm unable to get sound from my satellite system. I plan to change batteries in the remote later today. However, does it sound like a remote problem or that something is wrong with the receiver? Thanks forr any help.

Problem solved. Some dummy, either one of our cats or more likely myself, hit the 6-channel button on the remote and that screwed the deal up. Thanks to those of you who thought about my problem.

Since you resolve your own problem this thread will now be close for posting...
