I have the Sony STR-DH820 and its great but is there a way to listen to the built in FM radio while I watch Cable TV or while i play a PS3 game? I wanted to listen to the local radio football commentary earlier but had to stare at a blank TV screen showing HDMI 1 in the corner!! I can put freeview on the TV but this is not ideal. All my sources except the Wii are HDMI (TIVO & PS3) and go through the AMP so to my TV see's everything as the HDMI 1 channel. Have looked at the manual about 10 times and there is a section on changing inputs and also a 2nd zone but neither seems to work for me. Any ideas experts?
