It definitely seems to be in the recording, because the preview image in the Watch Recordings screen shows it to.  Usually its blinking/flashing green dots/lines at the bottom of the screen.

So its something in how MythTV is processing the image -- both for preview generation and playback -- which is causing the corruption.

Interesting. Does the preview generation also involved VDPAU?

I wonder how many forms of this we have. So far two have been descrived:

1) The whole bottom line is incorrect, and is a solid single colour.

2) Only the first 3/4 of the bottom line is incorrect and consists of
3 copies of the last 1/4.

Who's seeing which? I see No 2.
