I'm sorry Reimar, I guess I should start over with a better explanation 
of my setup.

I'm on windows xp, using 2 nVidia 8800GT graphics cards, with 2 monitors 
attached to each.  My first monitor is 1600x1200, on which I run my 
control software (in java), and the others are used for display (ie the 
3 separate videos I want to play, one on each monitor), ultimately being 
connected to video projectors. 

Since my first monitor is larger than the rest, I can't (or at least I 
don't think I can) use nvidia TwinView, or whatever they call it, to 
"span" the 2 monitors on one card into a single "virtual monitor", for 
lack of a better term.  I instead use the nvidia control panel to set 
all 4 monitors up as independant displays.  Then, in windows, I extend 
my desktop onto each monitor.  This is done by right clicking the 
desktop, choosing properties and then settings to get to the windows 
display setup tab and clicking the "extend my windows desktop onto this 
monitor".

I've been doing this sort of setup for quite a while on different 
machines and haven't run into any issues with other apps or my own 
programs, that I've been aware of, although of course the problem may 
simply never have manifested itself in this way.  While I believe that 
the directx driver will allow me to position the mplayer windows 
anywhere in "windows desktop space", I'm not in the office today and 
can't really re-confirm this on my setup.

This setup works well for me overall on my other projects, but I'm 
willing to change it if you think it will resolve my positioning problem.

Finally, my ultimate goal is to be able to start 3 different mplayer 
instances, on monitor number 2, 3 and 4.  A secondary goal is to be able 
to have an mplayer window spread across 2 or more monitors in certain 
situations.  Note that I can do all of this by starting the instances of 
mplayer and then dragging them to where I want (if I use the gl2 
driver), but I can't create them in place, which is what I need to do.   
It's certainly possible that I'm making this more difficult than it is.  
Any advice on reaching this goal is greatly appreciated.

thank you for your help,

morris
