I had this problem on my onkyo txnr 838. I found the DVD input worked best and changed cables and the problem stopped and works fine now. Was doing all sort of crazy stuff before. Btw onkyo discontinuing support for siriusxm has been a real let down. I finally got an onkyo rep to admit they had a falling out with sirius and will not enter an agreement for streaming their service thru onkyo. Sirius was cutting my onkyo off after 20 minutes. Enough people must have complained and the service works again, but for how long?
