Mandrake: Mine just says NTSC on the back and plays on all 3 dvd players here. Mind you my magician protege had a list of 'numbers' which he entered and our players/recorders seem to play everything.
Cannot remember where I bought it from, NOT Amazon I don;t think?? but it was off the Internet.
Dale: Heavens & Abracadabra, WHAT a missed opportunity.
Most professionals will welcome the amateur & semi pro. I'm sure DH would have.BUT you backstage visitors, choose the right time, AFTER the show and NOT on the last night. Get permission FIRST. Remember your manners. The Great One has just done a show. Don't ask how things are done and DON'T, as 2 magicians I used to know, take a tape measure to measure up the dimensions of the illusion boxes!!
The only one that didn't was when Leslie Melville & I tried to meet Jasper Maskeleyne backatage at Dudley Hippodrome. We were both 14/15 at the time.
It didn't help matters that we'd both gone up on stage to assist him in Selbit's Through The Eye Of A Needle (The 2 barrels with a steel plate in between and a girl passes through it), and Leslie, testing the steel plate was real, smashed the wooden mallet.

To this day he denies he broke it!!
Little did I think I'd a stand in the same spot on that stage, 2 years later,winning Opportunity Knocks with my Vent Act.
All I could think about was..'Dante stood here in 1947!'
