This is normal. It first tries to use Xv to do the scaling which should
be quicker because it uses the hardware scaling in the graphics card. If
your card/driver doesn't support the format we need then it will do
software scaling and use XImage to display the frames.

Press INFO to toggle the order. It will remember your chose and use it
the next time the event list screen is shown. You need at least r12925
for this to work - looks like you have r12930 so should be OK.

I think I have spotted what the problem is. There is an initialization
problem when switching monitors that have either different capture
palettes and/or capture resolutions. If I get time I'll take a look at
fixing it this weekend.
