Last spring I made a stack for the local school district.
Its a front end to a National Geographic LaserDisc about Birds.
The LaserDisc had two sides full of typical nature show clips of birds
doing their birdlike thing.
The stack I made lets you jump around this laser disc (side 1 anyway)
The stack will work perfectly with other discs but it will jump to 
odd scenes as the frame numbers are coded into the stack.

Even if you don't have the specific laserdisc you might get some ideas
on how to sscript for laserdisc control.
Especially look on how to store the frame numbers in hidden fields and 
then pass those frame numbers on to the xcmd's like
searchVideo
play video etc.
Once agin the stack is on my machine at work.
The ftp site number is 137.229.30.20
Log on as "anonymous"
password is "guest"
If someone would like to upload it to the info-mac archives go ahead
Also be patient as my Mac running NCSA Telnet can only handle one client
at a time.  I noticed that the machine was busy most of yesterday
sending out Supremacy.  The stack is in 2.0 format.

Ant Man!
