I got a Motorola DCX3400M last month. We almost always watch HD feed, but every now and then, we have SD stuff to watch. When we do, rather than switch automatically to 480p, it stretches the screen into 1080i. I know I can manually switch it with the "format" button on the front of the PVR, but that's a pain in the rear. I've searched all though the menus and I can't seem to find a place where I can set the PVR to automatically switch to whatever video format the box is receiving. I know it's not our TV, b/c our old Pace PVR automatically switched.
I'm guessing I'm being dumb and just missing a setting somewhere. Can anyone help?
