Hi... On my Viewsat Extreme...when I change the channels...the top info bar like satellite, pip and theme...and the bottom info box with the channel name, guide info, sig & qual info and time...are flashing repeatedly...over and over and wont stop. I have to press exit to clear it...is there a way I can fix this??...everything else works fine. I have tried power down and reboot but still the same thing. Thanks for your help.
