You say your files are AVI, but you didn’t say what codec they use. AVI is just a container that holds codecs. If you had a complaint that your soda tasted funny and the customer service person asked what kind of soda it was and you said, “It came in a can,” your response wouldn’t be very helpful. You should say, “It was a can of Pepsi and it tasted terrible.” Then she would say, “Ah, I see your problem. Here try a can of Coke instead.”
Now, you say this type of file worked before? In addition to asking what codec these AVI files use, what is the source of them? Have you tried importing a file that you’ve used in previous projects? What version of Windows are you running? Have you tried doing a system restore to before the update?
