No prob, I guess I deserved it ;)

Hmm... I did the quickest fix but in thinking for the src/ implementation,
I think that the basic VobSetVob should not be boxed - the subclasses
should decide.

Maybe the right answer is to make *that* efficient...

An alternative would be not to clip but to cut the string and draw
