Thanks for the suggestion Jeremy, but it cannot be exactly that, because the
image file is only 1265MB, while the disc capacity is 4GB IIRC.  However I
agree with the similarity of the symptoms, and agree that it does /seem/ to
point towards how CDVDB recognises the disc, or not.

Here's a bit of serendipity I wasn't expecting.  We are using !CDROMFS now,
and I was surprised to discover (by accident) that by double-clicking the
ISOImage file, the contents are readable!  I vaguely STR reading about this
somewhere, but I had forgotten.  A useful feature (if only they could be
writeable as well!).  As well as checking image contents, it is possible to
verify image contents in this way by dragging them to a null device window,
though whether this is useful or not I don't know.  (I always do this for
burned discs in any case)

Steffen seems to be away ATM, but a happy New Year to you and him when he
comes back
