If the overlay code only has advantages compared with the textured code, 
on the hardware that supports it (like the 945), I wonder why the 
decision was made to make it the second adapter?

The driver code decides which xv adapters to initialize based on chip 
set, but now it always adds the textured first if it can.

While Mplayer can take a command line argument for xv port, I believe 
xine and mythtv don't have the option and just pick the first.
