I have several .avi files that I have recorded on my digital camera and uploaded to my MacBook over the past several years. At the time I first uploaded them, they worked fine. But now, when I try to play them, Quicktime just shows the first frame or a black screen and the cursor (or whatever it's called) moves very quickly from the beginning to the end. Also, when I CMD+I the files, it shows that they're only a few kb each. Now, I've gone through these boards and downloaded just about every app, player, codec, etc. I've seen mentioned, and nothing has helped. Any thoughts? Just a little more background: these files have gone back and forth from my external hard drive to my computer several times over the past few years. Could this have caused the problem?
