When we did the presentation system for the DoI we found the same problem.
Apple in D.C. and in Dallas had the video stack, but the Sony drivers were
conspicuously missing from both.  As a solution, you might want to look at the 
HyperTerm stack which contains generic drivers for the serial ports.  Then
write scripts that act as a shell around these XCMDs and XFCNs.  You can have 
more flexibility here since you can fake playing a long segment by sending a
"play" command, and monitoring progress via. an Idle handler.  This way the
player won't be locked into playing a sequence, and can be interrupted at any
time.  Also it returns control to HyperCard before the video sequence is
complete.
