This TV is really great. The only thing I cant figure out is how to get the spdif to pass anything other than stereo from the HDMI. The manual seems to indicate you can pass Dolby Digital as well, and there is a setting for choosing one or the other, but in either case it only passes stereo for me.
I just read the manual, and it does not say anything about passing audio through from HDMI. It says there is an option to turn it from Dolby Digital to PCM, but that's it. Most tv's don't pass through 5.1 audio anyway.
