Well Ripplin, although one problem is more or less solved, this brings us back to a problem I had a few months ago and was never able to resolve: Sony Vegas will NOT play AVI files for some reason! (It did on my old computer, but that computer was more or less unusable anyways)

If you still have your avi files can you load up one of the files into virtualdub, select a small section (only a couple of seconds worth) and export the file using "direct stream copy" and then upload the file to rapidshare or somewhere and i will test the file out in my vegas and i may be able to figure out the problem for you
