        I'll check it out when I have nothig better to do!  I've given up
        on copying the one commercial DVD but still want to back up my
        Jos Campbell DVD.  Before it gets scratched up.  Or lost.

        It wasn't bad enough that Ol' Walt loved Uncle Adolf; but 
        the corporate culture hasn't changed that much now, has it?

        Well, if it takes messing with Dos: no thanks.  for as little as 
        I watch any video, if I can't tape it off PBS, then I'll buy 
        whatever DVDs there are.  Just a shame that I can't make a backup.
        Oh-well.  Compared to all the rest of the BS and global problems,
        *this* issue isn't even a hill of beans.
