Advertisements Using cable w/o a cable box the channels are out of sync. Sometimes when I get to a channel the top of the picture is showing up in the middle of the screen with the bottom part wrapping to the top of the screen. If I change the chaneel it sometimes fixes but not all the time. What could be causing this issue? **It should be noted that I recently added a second hard drive to my series 2 540 using the weaknees tutorial.
