After approximately 5 months of smooth operation with full 7.1 configuration (very happy with the overall quality and power!) I have started all of a sudden to experience problems with my AVR250. The symptoms are: ANALOG mode (input from Sat, Xbox): Loud static noise (I believe it is described as frying bacon) over the original soundtrack that sounds garbled. DIGITAL 5.1 Mode (DVD from DV78 Coax): Inconsistent behavior; sometimes it would decode smoothly, or not decode at all or may sound garbled. DTS (DVD from DV78 Coax): Last I tried was OK Anyone experienced similar symptoms? Is there a quick fix or is there is something terribly wrong with this receiver? Thanks!
