[mythtv-users] Svideo Tearing

Tearing has nothing to do with interlacing.

Tearing occurs when the painting of pixels on one section of the 
screen lag behind the painting of pixels to the rest of the 
screen.  In my case it appears that on fast side to side pans, blocks 
of pixels at the top of the screen noticeably lag behind the rest of 
the updates on screen.  It is a slight lag, but is an annoying 
artifact none the less.

This only happens on svideo out and not on the CRT.
