I have Mandrake 9.1 installed on my notebook: Compaq presario 1800T, UXGA 1600x1200, ATI Rage Mobility 128.
When I launch any video file (mpg, avi) - I see left half of the picture stretched to the window. The other half of the picture I don't see even if I resize the window, make it full screen, of try to change scaling format. It happens with all players I've tried (Xine, Mplayer, the one is default in KDE 3.1 browser - all of them showed the same picture).
I tried to play with video outputs in mplayer and figured, that sending output to x11 I could see the whole picture but only in original size (if I put it on full screen it just would show me the same sized picture in the center), gl (shows normal sized picture, but is slow ( frame per 2 sec), sdl (honestly don't remember, but not a satisfying result either).
The default video output is xv, which I assume the other players use and which has the problem described above.
On my desktop I have the same software installed and everything works fine! Mplayer prints the same text in console after playing video file.
What may be wrong with xv vo? How may I configure it or find the cause of the problem and solve it?
Any ideas? I couldn't find anybody with the same type of problem or a solution for it! Please help!

maybe the xv driver interface for that card isn't working correctly. on mplayer try x11 again with the -zoom option, that'll will make it scale on full screen..

I would rather like to make xv output work correctly, so I could use any player and not only from console and on full screen.
When I start Xine, it even shows halfe of the XINE name in the video window.

Is it possible to configure xv? What should I do?

well i can't really think of anything offhand, if it starts to load then xv itself is obviously on your system (run "xvinfo" to double check), other than that... try a differetn color depth and resolution, might be a glitch there...

The problem is solved by replacing the ATI drivers from here:

Just copied the files and now xv output works fine.

P.S. Btw x11 with zoom option still was impossible to use because it needed more that 100% cpu when scaled
