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.

Perhaps you did not realize that you need to put a blank (color zero) screen into your flow before the video icon, since effectively you want to genlock with a blank screen in this case. (Depending upon your pallete, you can normally just put an empty screen icon in the flow to get the blank screen you need.) >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.

The one screen solution is a key advantage in terms of cost and ease of use. Most Mac people I have dealt with are used to a two screen approach, but clearly a one-screen solution is what the users generally want. >Any solution, or even hints or suggestions, would be greatly >appreciated.
