If you can see the contents within the command prompt (cmd), your cd-access driver should be ok. Besides that autorun works, too.
You say the explorer won't open it. Does this mean, that it crashes or does it hang?
Already tried to disable 'autostart' (this causes more problems than it is of use)?
You could get access also via Isobuster, but the command prompt (whichs is mostly faster than a GUI, anyway) is probably the easier solution.
