The latest Sony LDP 3600 is reputed to play NTSC and PAL discs.  Similarly,
Sony has for some time made video monitors which will accept PAL, NTSC or SECAM
mode input.

We put out a product, POSSUM (Pictures of Standard Syndromes and Undiagnosed 
Malformations) in PAL and NTSC.  The generic master is on 35mm film, the first
dub master is on one inch PAL video tape.  It is now well within the state of 
the art to transfer images from PAL to NTSC.  The only catch is that if you're
transferring stills, you need frame-by-frame accuracy; if you're transferring
movies you use five NTSC frames to generate six PAL frames.  The NTSC to PAL
conversion and vice versa is routine in the domain of TV.
