Just noticed some feint sounds of music coming out of one of the speakers on the extigy (which is hooked up to a pansat 3500sd) when the tv is on White Springs channel - the music isn't the sound coming from the tv channel. I can hear the tv channel's sound on the tv's speaker. I'm guessing this is some sort of signal leak from the radio station that is on a nearby tp. Does that happen often when tv and radio share nearby tps and you have a speaker hooked up to dolby digital?
