I have a QIP6416-1 set top box. As of last night at ~7 pm, the TV guide was displayed in widescreen format. Sometime between 7 and 8 pm, the TV guide went to a 4:3 format, with black bars on the sides. There wasn't any software update, and I didn't change any settings (to my knowledge). I have unplugged and rebooted the set top box several times, tried the In Home Agent, checked all video and channel guide settings to no avail.
Is there a setting that I'm not aware of that needs to be change, or is my set top box fried? I've had it at least a year (probably longer), and it has always displayed the guide in widescreen until last night.
