I have Verizon FIOS (Motorola HD DVR box), Vizio 47 HD 1080p, and a Phillips HTS3565D Home theater. I cannot get the FIOS remote to recognize the Phillips system. I need to do this so I can control the volume from the FIOS remote. I tried the FIOS '922' search function multiple times (cycled thru more than 200 potential codes) and came up with nothing. Any idea what I should try next, or am I hosed? thanks
