problem with imgtools and playback on computer

[gnutellafan]

I am using imgtools.dll 0.89 w/ ifo edit to creat DVD images. I then burn the images w/ DVD decrypter. The burned discs work fine on standalone players and my xbox but cannot be read in the computer, even the drive used to burn them. The image is mounted but cannot be read by deamon tools, but can be analyzed using isobuster.

Any ideas??
