Picture Too Low on Some Channels

[new350user]

Recently I started getting white wavy lines across the very top of the screen on some channels, like the picture has shifted too low on the screen for the bad channels. I have changed nothing with my PVR-350 or GB-PVR, and some channels are still fine.

The Tuning Assistant also shows the same problem. I assume something has changed at my cable provider (Comcast analog), but is there anything I can do to correct this?

Is it just like 5 pixels high? If there is ClosedCaption data or TeleText data, it is sent as part of the actual image, right on the top of it. A "normal" tv never (?) shows the entire image, but uses overscan to crop the image on the edges, so that you don't see the ClosedCaption/Teletext data. Could this be what you are seeing?

thats what I see. I noticed it was'nt part of all programming and now I know why. It came and went with different shows on the same channel.

is there a good way to hide it?
