   I'm getting very close to having snapshots.  I am actually thinking that 
maybe it is LCD related though.  Do you use an LCD display?

   And no I don't have PAL here.  If someone wants to send me a PAL capable 
DVD player and some PAL dvds I would gladly test PAL too though. :-)

   Great!

   There is a bit of a snag here, and I think it's not really necessary to 
work around:

   When you open a device with one plugin or the other, it remains open and 
locked.  Thus when we re-probe, we find that the old device is no longer 
available.  We can't assume that it still is because it might have been 
physically removed from the system.  If we close the old device every time 
the change source dialog is opened, I suspect people will become rather 
annoyed.  It's a lose-lose situation in my eyes.

   The real question is, why would anyone want to use the same v4l device from 
both v4l-direct and v4l-xv-bridge?  This is more for development purposes.  
After that, the device will be either v4l or Xv, but not both.
