Perhaps it is easy to implement it or maybe not, but I think it would be a great improvement to your program: Allow DOS/ASCII Characters in ISO9660 Labels if DOS/ASCII is Set, because if one is already allowing DOS/ASCII characters in the file system, why do not the labels?
Another thing I wanted to ask why it is so if one leaves the Volumes Identifiers in white, 2 of them are filled with:
Volume Set: UNDEFINED
Application: IMGBURN V188.8.131.52 - THE ULTIMATE IMAGE BURNER!
respectively, it would be nice to come pre-filled data and if one could remove what I want, not vice versa. In addittion could be implemented to filling the data: Copyright, Abstract and Bibliographic who would like to fill them.
