I recently purchased a new HDTV and exchanged my old box for HD. This box is Xfinity. Although it is working fine, I do not have a manual to help me use the remote effectively. At first, I could toggle with the Zoom button to view pictures in several shapes and sizes. At the present it is locked into one mode, full screen and will not toggle. This is my immediate need for a manual or help, but would like a manual in either case. Thank you. Pat Millman
What type of cable box do you have? It sounds like it's set to display SD in Stretch mode, which may conflict with your TV's settings, causing double-stretching?
For a Motorola box:
Turn it off, then hit MENU (you can do this any time it is off).
TV Type should be 16:9
HDMI/YPbPr output will probably be 1080i
4:3 Override should be 480i (my preference for SD). This way, your TV will upconvert to it's native format, and most TV's also have separate memories for HD vs SD, allowing you to configure them separately. If this is set to Stretch or OFF, the box will do the upconvert, and your TV will never know the difference.
Is anyone having problems with seeing their channel guide change when going from HD channels to non HD channels?
On HD channels the guide looks great, however, on non HD channels the guide is too spread out so we have the change the TV screen settings to see everything. Then you go back to HD channels and the picture has changed, so you change the TV settings back to watch a little HD then you flick to a non HD setting and you can't read the guide, so you change the TV settings again. This is ridicules and very aggrevating....any help out there?
