I recently picked up a Mits 57831 DLP TV. Very happy with it so far, but I was surprised to see there was no optical audio input on the back panel. I have a Motorola cable HDTV STB that outputs component video and digital optical audio out (as well as standard video and audio out, but those are being used by Replay TV). Currently I have the optical out going directly to my receiver, but for various reasons (mostly having to do with watching PIP split-screen) I would like to run the digital audio out through the TV. The only thing I can figure is to try to find a Y-adapter that will convert digital optical audio to RCA L/R audio, but apparently that would require a digital-to-analog encoder of some kind. Can anybody help me figure out how to convert digital optical to RCA analog? I tried a couple of cable companies and Radio Shack but no dice. Note that the STB also has SPDIF out, but that would involve the same problem as optical. Thanks!
