I don't see any instructions for the STR-DE197 in the otherwise excellent instructions posted in the Sone Remote forum. Do I need to switch to AV-1? I've tried using the instructions for the STR-DE597, but it didn't make a difference. Any thoughts about what else to try? I am able to get my Sony CD changer, Phillips TV, Panasonic VCR and Panasonic DVD to work with this GE remote, but no luck so far with the Sony receiver. TIA
