I just upgraded to the vip 211 receiver from dish network. Almost every time I change channels (90+%), the info section blinks about six times and the format size changes about six times also. The screen goes black with grey side bars and finally, after about four seconds of this flipping around, the channel comes on. Very annoying. I tried to find anything in the receiver setup to change with no luck. I also tried to find something in the tv setup menu to turn on or off. Also no luck. Maybe the receiver is just bad from the box? Any ideas? Thanks.
