I need to get videos to TV with full screen. My graphics card is GeForce 4 MX 440 and TV connected as clone with twinview. My primary display is 1280x960 and my TV is 1024x768 with 1280x1024 virtual display.
I'm using Debian sarge with 2.6.8-2 kernel and Xfree 4.3.0.1.
One way I think would work is to make TV show my whole screen at once by dropping some pixels off so 1280x960 screen will fit to 1024x768 (or smaller).
As video player I use mplayer, so one way would be resizing mplayer output window.
Problem is I don't know how to do neither of those.
I don't care much what way I get it working as long as I can get it even working somehow.

Using MEPIS, my card has the option for twinview and these things, but they always seem to screw it up, especially if I select TV as the other output. The nvidea 5500 card that I have (I think?) just automatically puts the screen output to the TV and so my TV looks like my screen; I just maximize my video on screen and its the same on my TV and there is no config to deal with.

i'm not too interested in changing distro. Can I get video full screen for TV with my Debian?

I did this some months ago, I hope I remember correctly:
Start mplayer from shell with option -xineramascreen 1:

Maybe you need quotation-marks, I don't remember. Just try it out!
