so i just set up my new phillips magnavox 37" lcd hdtv... but what's this? the only audio out is a digital plug, labeled "spdif out". my surround receiver has only analog signals in, the red/white plugs. can this work somehow? well off i went to best buy and asked their av guys about it. they recommended a quality 6' cable and an attachment that split it into two plugs at one end. well... it works, but it sounds atrocious. the signal is garbled and static-filled, this solution did not work. i need a better solution. tv model is magnavox 37mf231d. it is phenomenal audio receiver/amp is an optimus stav-3770 pro series. it was great 6 years ago when i purchased it any suggestions are appreciated, i could really use some help, thanks!
