Pls Help - Fujitsu ST4110 with Vista - Video Playback problem on W

Dear all,

I just spent the whole weekend installing (4 times) Windows Vista Home
Premium on my Fujitsu Stylistic ST4110.

Straight out of the installation, the native video drivers had this problem:
- Playback of any video MPG or WMV was choppy and jerky on WMP11 but Audio
was smooth.
- Screen cannot Rotate.

I tried installing the latest Win XP Drivers and most everything work. The
only problem I had was:

- Now WMP11 cannot play any video (get a blank video screen) but the audio
continues in the background. Tried MPG, AVI, WMV... all can't. When I tried
using VLC player, there was no problem and playback was smooth with audio. I
suspect this might be a problem with the video driver.

It won't playback either on Windows Media Centre. I suspect that it may be a
Video Driver problem but Fujitsu has not come out with any Vista drivers for
my graphics card ( Intel 82830M ).

Does anyone have a suggestion on how to fix the video playback problem in
WMP11?

Thank you.
