I copied this post from another thread hoping someone might have some insight into this problem.

I have just connected my Motorola 6412 and Denon 2910 to a gefen HDMI switch. I can switch back and forth between the two just fine. My problem begins when I leave the switch on the DVD for a long period ie. watching a movie. When I switch back to the 6412 cable box the cable box settings have changed from 1080i to 720p and the screen size shrinks. Once I change the settings back to 1080i everything is fine again until I watch a movie.
I have sent Motorola a email but their person replying really didn't understand my question. I will call them next and see what they say. I know my cable provider will have no clue!

After conacting Motrola they tell me the cable company needs to update the units firmware to v12.23. Mine currently has v12.22. So I call the cable company and to my amazment they have no idea what I'm taling about. So after the girl checks with someone who is supposed to know more she says they will send a tech out to look at the box. I'm interested to find out what the tech knows about this. Seems to me that the cable company should be able to flash the firmware update from their location and restart the box.
