My son just got a Sony TV (KDL46S5100) and a Sony receiver (STR-DN1000). It would be great if the Sony remote that came with the AV receiver (remote model no. is RM-AA P040) could be programmed to work with the Comcast HD/DVR (Scientific American RNG200). If not, they'll have to get a universal remote that does. So, can the Sony remote be so programmed, and if so, how? Thanks much.
