I've got a R22 DVR+ on a standard def television. All of the channels fill the TV screen except my local channels which have a gray bar at the top and bottom when the station transmits in HD. When it is a non HD format it is also croped on the sides. I was told by the installer that the once the switch to digital takes place that the stations will be displayed in full screen. Is this correct? When I contacted D* tech support they didn't know anything about this and they couldn't figure out why I wasn't receiving the picture in full screen format. They had me do a reset on the receiver but it didn't do any good. Am I stuck with the gray bars???
