MP4 decoding with SP2 - anyone have a clue?
 

I have a set of clips that are in MP4 format, and i cant get them to play with anything ever since i installed SP2. Before SP2, they played fine, and went through the video decoder fine, but now i seem to be up the river without a paddle. I need to convert the clips into mpeg's and wmv's - but i get errors when i try to load them with anything (cleaner 5 = Unhandled exception: 0000005; At address: 66a97a3f)

Any info guiding me to a resolution would be greatly appreciated.


Thanks
