i am having problems with my 612 receiver while i am using the interactive weather on the weather channel. it loads good but since the app doesn't support widescreen tvs it puts the black bars on the edge of the screen. so my problem is when i exit the app the black bars on the edge stay and will not leave without doing a reset on the receiver i have tried pushing the format button and still it will not go away. is there any fix for this without having to reset receiver?
