Mitsubishi receiver decoder message

After about 10 to 15 minutes or so, the receiver will stay on the input of my choice, and play just fine, but periodically switch back to input 4 and display "decoder". It seems that after a while of playing, it will begin to switch back to input 4 more frequently.

If I hold the button for the input of my choice, it will stay on that input and play, but I worry this is leaving some switch open and will burn something out.

If I hook up a music source to input 4, it will play when the machine automatically switches to "decoder", albeit with a much decreased s/n ratio. If the s/n ratio wasnt so much poorer, i'd be fine leaving it how it is, as the music comes through.

From my experimentation with my vr-800 model, what I've found is that the decoder display occurs only when there are multiple inputs to the receiver that are all actively playing (Video 1 - roku, video 2 computer s-video, dvd - player). If i turn off the computer input and dvd input so that there is just 1 signal then the receiver no longer seems to switch back to video 4.
