Ok, here';s my problem. I have been merrily shrinking and burning my DVDs using Shrink and Burnatonce with absolutely no problems (and completing both processes in less than 30 minutes!). All of a sudden one night, I start getting error messages from Burnatonce that say "wrong disk". I switched the disk for another one, got the same message. Tried another brand, get the same message. Downloaded the trial version of Nero, and got a similar message. Tried in on the program that came with my PC (neoDVD) and got a similar error message. So I can't figure out the problem; it's got to be the drive or the media. In reading some related threads, I see that perhaps I should uninstall the drive and let XP reinstall it. Is that the solution? Also, what may have caused the problem? Thanks in advance for all your help.
