Reposting from multiple sources.It seems like most (maybe all) Sony HTIB do not work with the Comcast Custom Remote. I've found a work around that fixes the volume control and power button though. Hope it helps you all. I have a DAVHDX275 but I think this will work for most Sony HTIB systems.What you need to do is steal some codes from a like product and then hardcode in the changes you need to the comcast remote. Set your AUX to 21232 (a sony code for TV/VCRs).Then do the following:1. While still on AUX, press and hold SETUP again until the remote blinks twice2. Type 9943. Press and release SETUP4. Type 329755. Press and release VOL+The remote should blink twice. That should reprogram the VOL+ to work with your Sony HT device. For each of the following function codes, follow the same steps and use the codes listed below:Vol+ = 32975Vol- = 31951Power = 32719
Mute = 33743Good luck. Let me know if it works.
Also, to program your remote to function volume controls while in CBL or TV mode without switching between modes to change the volume, see below. Source http://www.hifi-remote.com/forums/viewtopic.php?t=8831Quote:
Locking Volume Control To TV or AUX Mode:
1. Press and hold SETUP until the Red light flashes twice, then release SETUP.
2. Enter 9 - 9 - 3 (Red light will flash twice).
3. Press and release either TV or AUX (Red light for selected device will flash twice).
