I want to create a movie in VMS10 which will be used as menu in DVDA, with buttons add as a layer in VMS
and to somehow link them with the movies or slideshows
in DVDA. is it possible?
Yes, as musicvid said use the video created in VMS10 as the menu background.
I've found creating menus in Vegas is actually a little easier and you have a lot more control of the button videos/images and can crate a more complex and interesting menu.
One method to associate buttons to the images on your custom menu video:
-Create the menu video with all the buttons and/or videos on it in VMS10.
-Import the menu video into DVDA.
-Import your video(s)
-Use text only and a blank space for your button, position the "space" over the button locations and size it to the button.
-Link it to the video(s) in the DVD.
