I am attempting to develop an interactive videodisc presentation
using an Amiga 2000 with a Commodore 1084 monitor, 30 MEG HD, and 
7 MB Memory, connected to Pioneer 2200 Laserdisc player and a Super
Gen genlock, and using AmigaVision as the authoring system.     

Here's the problem:  after generating a number of menus and inserting
the appropriate frame numbers from the videodisc I try to "Present"
this interactive program.  The results are not what I expected.  The
movement between the menus works well, but when I attempt to make a
menu selection that will play a videodisc sequence the menu fades to
black and then immediately reappears while the videodisc sequence
plays in the background.  The question is: how can I get the menu or
graphic to disappear from the screen until the videodisc sequence is
played and then return after the videodisc sequence is completed?

Maybe AmigaVision requires a two screen setup where the menus appear
on the Amiga screen and the videodisc sequences appear on a second
NTSC monitor.  I've tried this two-screen set-up and it works, but I'm
still hoping that a one-screen set-up will work as well.

Any solution, or even hints or suggestions, would be greatly
appreciated.  Thanks.
