Whats wrong with my card?

My ATi ALL-IN-WONDER VE TV tuner card used to worked just fine, untill now.
Now I am stuck at 1024x768.

When it tries to go lower, the screen gets like, all scrambled.

It used to work just fine, even on knoppix 3.7, 3.8, and 3.9. (I am currently using 3.9)
It worked on 3.9 for a while but when I go at resolutions lower then 1024x768 it get's all scrambled....

I havn't tried any older versions of knoppix yet.


What would have gone wrong?
Is there any way I could use windows drivers?
