At MacWorld Expo, ACIUS was demoing a 4D application which would control
a videodisc player, a VCR, and launch animation sequences from MacroMind
Director.  I didn't have more than a cursory look at it, but it would
seem to fill the bill.  The developers were two guys from ACIUS (Todd
Carper and A.J. Jennings, I think), and it will eventually be sold for
$200, but someone at the company may be willing to discuss how this can
be done in a generic way.  Since the original sender is from Stanford,
he may be able to talk with one of the developers in person in Cupertino.

Yes, I have a bit of experience implementing laserdisk control (I'm
using a Pioneer LD-V4200) using serial port primitives. I haven't implmented
every feature that the player supports, only those my project has required
at this point in time. Still, I'd be happy to discuss this with you.

Also, I am in the process of adapting some Hypercard XCMDs -- not for
laserdisc control, but for controlling a RasterOps digitizing card -- for
use in 4D. I'll be using a program called XLink to do this. Again, I'd be
happy to discuss it, since this would directly apply to adapting XCMDs
that control laserdisc players.

Why don't you drop me a personal email message...
