The information provided did not solve my problem of not being able to control the referenced device with the Comcast Cable remote control. I already had tried the audio receiver codes provided were apparently not for the RTD315W Home Theater System even though the Comcast remote control recognized them. The other code you provided may be the correct code but just not in the remote database because it was not recognized by the remote controller. The unit has a remote control for its use so it obviously has an assigned device code. There may be a way to program the Comcast controller with the other remote to find the code. I will contact the cable company this coming week. Thanks for your help.
