Just got my Sony NSZ-GT1 and i really like it. I had to go down to Comcast and swap out my old DVR because it didn't have a HDMI port on the back. So today i got the new one and hooked it back up, and i can't seem to get the sony remote to control the TV volume, TV on/off, and Input buttons to work on my TV. My HDTV is a Panasonic TH-42PZ80U 42" Plasma. It's weird, because when i initially set the box up (before getting the new compatible cable DVR box) and following the first-time setup, i wasn't able to get the volume buttons working during the setup. I ended up just clickng "yes it works" or something to finish the setup. Then, about a hour later into using the new (NSZ-GT1), the volume, input, and power on/off buttons started working. Then, later, stopped working. Every time i try to play with the TV control in System Settings, none of the codes ever work when i select Panasonic as my TV manufacturer, just like they didn't work in the initial first-time setup. Would appreciate the help greatly.
