I have a STR DN1000 recv. that I am trying to pair w/ an ATT VIP 2250 dvr cable box using the S10-S3 black remote and a Samsung TV. I can get the tv and cable box to work but I cannot get the att remote to work with the receiver.I have put in all the codes listed with att remote , called sony and att. The remote is s10 s3. The recv uses sony remote # RM-AAPO40. Anyone have the codes to work with the att remote or am I doing something wrong. Thanks
