I have a set of 8 avi files, 3 of which have a problem. The only way I can play them is with VLC Player which says "AVI File is broken" but offers to repair it. This it does and then proceeds to play it perfectly well. However, the repair is not permanent. I tried using DivX Repair but that said the file names are invalid. Interestingly, normal windows operations won't work on the files either...can't delete, copy or move them and the only options available on a right click are related to Media Player or Send to.
