none of the above is the real solution to this problem !
I’m a developer of gfx-drivers for various cards so I investigated the problem and debugged the hell out of it with soft-ice debugger. It turns out you need the 3ivx codec.
directx looks makes a call to this codec and when it cannot find it, it uses the default win-codec which is wrong.
try it and you’ll see...
Dearest posters,
Does anyone really know the true nature of this problem other than giving 12 diffrent ways to solve it?
None of these methods worked for me, and considering some people just had it fix itself on its own I have a feeling in order for me to take a more direct approach I’m going to need to know a little more about the problem.
Can anyone help?
Melvin you are the best, thank you very much 
I tried doing what K-pax suggested but my quick time does not have video preferences its got Player preferences and quicktime preferences.
but nothing else Im not sure what else to do I have not had this problem before any ideas?
Worked for me too melvin, thanx
