I went through a similar problem at the end of last month and it took 3-4 weeks to resolve.
Here's a link to the discussion on UBIZoo Help forum (I'm being very unkind, theres actually a very positive feeling over there at the moment!)

I found the following information at a librarian's Blog! The information is way down the page by a guy called Ryan.

To disable ffdshow on Vista:
1. Start Menu type in search bar “ffdshow”
2. Click the ffdshow video decoder config program
3. Click DirectShow control on the left pane
4. Check the box that says “Don’t use ffdshow in:”
5. Click edit and add the .exe file for whatever game
<<<<
ffdshow is a crappy video encoder (I think it was installed with real player, Though I could be wrong, I was trying to get a video to play a while back and tried a few things!)The solution involves telling ffdshow not to do it's stuff when you run a program.
I also did the same with windows media player and I can now play videos without the same error!
All I can say (touch wood!)is that it seams to have worked for me! And it only takes a minute to do the search and see if the programs on your system.

Hope it works for you too.
