I recently upgraded my Sony hd100 to the hd200 and have been having some strange audio problems which weren't present with the hd100. I have the non-Dolby Digital stations set to play in Circle Surround. The audio connection is an optical cable (same as hd100). Everything is ok until the Sony warms up. When changing to a DD station, there is a electrical zap sound--then the audio plays fine. When switching to a non-DD station, the Theta shows stereo instead of CS, plays ok for a couple of seconds, then goes to DD and the audio dies. This is my second hd200 and Sony is sending a third. I thought I'd run this by the Theta experts on the tweaks forum for ideas/suggestions. Software problems ?/signal changes when unit warms up ? / ?????
Thanks for any help,
