I have a DVD that I got on Ebay. It plays fine on my home DVD player. But in my Computer I can see the files but they are all showing up as 0 bytes. And will not play or copy. The used space on the disk is 3.99 GB. Any ideals on how to fix this would be great. I have AnyDVD it does not make a difference if it is on or off windows will only see the files as 0 bytes.
