#2 DVD ISO not supported

[jeppeone]

When I open an ISO file containing a DVD ISO image I get several printouts like the following:

++ WARN: could not retrieve file info for `<filename>.iso': Värdet för stort för definierad datatyp

All I wanted to do was to edit the label of the ISO image, but due to the above errors this didn't seem possible.

The ISO image was created by k3b, so it should not be anything special about it.

Since the file tree is parsed correctly seems to be only a few small corrections to make it fully functional with this format as well.
