Gotcha. I've dealt with my share of quirks as well. Everything seems to be HDMI related, video no sound, sound no video, only the right channel when playing music in stereo and they are all corrected by rebooting. I have a Dr. HDMI ordered as recommended (thanks Thxtheater) to see if it helps with the headaches.
It would be nice to get a new firmware that has the DTS changes and other updates as an official firmware release.
