it may also have to do with an additional TV-out and xv. At least on my 
system it does: on the normal screen I have 1280x960, the TV-out has 
1024x768, and it is a clone of the upper left corner of the screen. When 
going fullscreen on mplayer with -vo xv (default), the video plays only 
in the upper corner, and on the TV the movie fills the entire screen, 
and everything is fine. When I want to play a movie fullscreen on the 
computer monitor, I have to a) patch the xv that a second parameter à la 
-vo xv:full=1 sets the detection to 1280x960 (a really ugly hack) or use 
-vo x11.

My conclusion is that querying the resolution from X with this twin-view 
enabled returns only the lower of the two used resolutions.

Maybe there's a way to explicitly tell xv which of the monitors to use, 
but I didn't bother doing any more research into this matter, as the 
current patch works for me.

My graphics card is a GeForce 6600 LE, with Xorg.conf options:

Option 	"TwinView" "true"
Option	"SecondMonitorHorizSync" "30-50"
Option	"SecondMonitorVertRefresh" "50"
Option	"TwinviewOrientation"	"Clone"
Option	"MetaModes" "1280x960,1024x768; 1152x864,1024x768; 1024x768,1024x768"
Option	"ConnectedMonitor" "crt,tv"
Option	"TVStandard" "PAL-B"
Option	"TVOutFormat" "SVideo"



btw. Does anyone know how to avoid "tearing" on the TV screen, i.e. 
sending only a picture when the TV is doing a refresh or something like 
it. On horizontal pans this is sometimes quite bothersome...
