problem with graphics

I am on Compaq presario 6409TU with Xp pack2
Accelarator in use 945GM ExpressChipset family

The are 2 problems.
1>Game not working
i installed unreal tournament 2000 .. Theres a video intro wen the game begins.
The problem i face is here:
The video jus advances very fast ahead of sound
ie if total intro is 1min-- the complete video finishes in 30 sec ..
to put in words -- the video isnt a smooth flow .. but video advacnes in quick steps.
again this also affects the game .. In the game wen i move character [ie up arrow].. instead of advancing 2 steps (say) it steps more

2>The laptop comes with s-video out.
when i connect my television. i hear the sound of hardware detected[windows os detects it].when i click on graphic properties- ican see my TV listed and protocol is supported... but sometimes here at this point i hear a sound again .. somehow the TV display gets uninstalled and gets installed/uninstalled randomly.

if the tv does get the picture[ with repetitive effort ] -- i can see video clearly wen my laptop is on a battery ... wen i put main supply ON .. i see flickers on TV ...

Please help ... any any any any kind of help appreciated.or so
Thanks in advance

 

Um first of all I'd recommend downloading the latest drivers for your graphics. This is a good site: http://www.laptopvideo2go.com/
