DVD appears blank - but I know it's not!

[jamiesalisbury]

Hi all,

I've just acquired the Vienna Special Edition Plus sample library bundle (don't worry if you don't know what this is, it doesn't matter). The 2 DVD's for the the Special edition worked fine. The 2 DVD's for the Special Edition plus, which should be in a similar format, appear blank in the OSX window, and also in the browser window within the installer.

However I know they're not blank because I can see all the files when I insert the DVD in my PC. The window in OSX just says "0 Items 0kb available".

Any pointers on how to make the files magically appear would be much appreciated!

I have a PPC G5 with OSX 10.4.11.

Many thanks

Jamie
