Are you certain that played videos are:
YV12: 640x480
YV12: 480x576
The latter seems an odd resolution.

The blame does point to the video engine not idling properly. The 
flashing is caused by Video3 still trying to display with its old 
values, and thus, one in three frames or so are displaying fb content 
that wasn't written to since the 640x480 video, the other 2 should be 
older content from the current stream (in the wrong position).

This could be another or the same VT3122C issue, i'm now going to 
confirm this by testing both VT3122A and VT7205A.
