I described this flickering here:
http://www.gossamer-threads.com/lists/ivtv/devel/32970

PVR250 with cx23416 do not have this problem. But I know that earlier 
revisions of the PVR250 with cx23415 (have a heatsink!) also have this 
flickering when losing sync.

The funny thing is that I cannot provoke this flickering even with a current 
unpatched driver.  So there is no difference with the patch. (I can't say much 
about ghosting - I always use 720x576. I will see next weekend if I can do 
more testings)

@ Ian Armstrong: 
Could you check if you can provoke the flickering without your patch, but with 
a driver that has these changes:
