DVD Encore and video overlay problems

Hi everyone,

I’m a new Adobe DVD Encore user and I got a big problem with the preview function of menus in Adobe Encore DVD.

I use Matrox G450 and P650 graphic cards in dual head overlay mode.
It’s impossible for me get a overlay to my tv with which I can see how the menus look on a normal customer tv.
I’m be able to see the video stream but not the menu itself.
I tried some options on the Matrox overlay configuration menu but nothing helped.
Watching a normal dvd (e.g. with PowerDVD) isn’t a problem. The menus appear on th tv. But not within the preview in Encore.

I’m an old DVDMaestro user and I hadn’t this problem before.

Any suggestions would be really apreciated.
