HELP! I tried to burn an iso image to a dvd, it burned to dvd, according to Express Burn, verification was ok. But then when I try to see what is in, or try to open the files, with explorer, I see nothing, empty, no files; with EBurn, tells me 2.4 Gb used from the disk, but I cant see any files. I have Win Vista. What I have done wrong? I purchased EBurn because I could burn ISO files, but do i need another program to open or see the iso files? Thanks! Ceci
