I had 2 630's installed today (about 4 hours ago). #1 rebooted about 20 minutes after the installer left. #1 and #2 both rebooted at the same time 3 times after that. The only thing I changed was to only show the channels I get in the guide, and I changed the remote frequency on my Toshiba.
Everything on my Panasonic (#1) is working, but on my Toshiba (#2), the HDMI would not change the aspect (I had a reduced image on screen). I hooked up component cables, and that worked, but the picture was crappy (red). My son played with some settings and got the HDMI to work, but now my volume button isn't working.
Audio settings are Audio Connections - TV, Analog Audio - Surround, HDMI Audio - Auto, Digital - Dolby
Video settings are Output Format - HDMI, 4x3 Override - 580i, TV Type - 16x9
Firmware version is 00.10 on both.
blah, while I was typing this, #1 rebooted again.
