I have tried using multiple playback programs (mythtv, vlc, quicktime, 
etc.) and I'm confident the video file is not corrupt or being played 
back incorrectly. It is a problem during recording.

Has anybody experiencing this tearing before? My PVR-500 worked 
beautifully until I wiped clean, upped to FC7. Now I get this tearing:

Recently, I wiped it clean again and installed the latest version of 
KnoppMyth and still, the problem persists.

Any ideas? Firmware issue maybe?

Help!
