Writing long lead-out can be handled by drive itself and cannot be cancelled. It's not a bug, it's the way things work...

I'm writing a DVD Video burning program. While testing all the functions I discovered that when the burning operation is in the mode where it's adding padding to DVDs less then 1GB in size the Cancel operation does not work. For now I'll simply disable my cancel button when I get a CN_DVD_MEDIA_PADDING_BEGIN message, but this seems like a bug that should be fixed.
