Hello, This seems to be a classic quandary.Since Roxio will not cooperate, I am turning to my genus out there for help.. I can not see the DATA on hundreds of dvd-r dvd disks that I have burned information to. The disk are flawless as far as their physical status but the disks read full, but will not show any files. It might have something to do with the UDF reader not being properly installed on the disk.or it might have something to do with selecting different compression values on different disks, I made sure that I could see the information on the disk before I deleted the files so they should still be readable. But they are not. Save a soul from going mad !
