  Ooooh another RH machine.  I smell a trend. :)

   This ripping/interlacing stuff also seems to be a trend amongst LCD users.

  Something is not right.  Either you have an X server bug, or you are still 
somehow running old code.  Overlay is explicitly disabled in HEAD right now.  
See line 172 in qtvision_v4l.cpp:
        _useOverlay(false), _devMtx(true)
And line 505:
 if (_useOverlay && dev->canOverlay()) {

  That's the only place where overlay can be turned on or off.  So, what this 
tells me is either that you have old code (ie an old plugin or are pulling 
from an outdated CVS mirror), or there is an X server bug that is causing Xv 
to overlay on top of everything else for you.
