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...
