No I dont have LCD :(
A Matrox G450 card with XFree 4.2 (Redhat 7.3) on a CRT monitor.

Yes you are right.
Why I asked for this was that when you try to record under zapping it 
automatically changes to v4l mode, and you can easily switch back when you 
are done with it. (if I understand it correctly you can not do recording with 
xvideo).
But then you know that the user wants to switch driver, so that case is 
different.
