Greetings, I have been working on a video project which I am working on putting onto DVD. I have been using Sony DVD Architect. I created a main menu but I want to have a very short clip (around 5 sec) that would play immediately on clicking a menu link before going to the link the viewer selected. I am certain I have seen this done.. Can anyone help me out here?

you would need to set that particular button to point to the video clip you want it to play and then set the END ACTION of that clip to point to the clip you want to play immediately after that.
IOW it will take 2 actions to complete the action you want but it can be done.

Ahhh excellent thanks. One other question does the DVD standard "support" widescreen menus? All my source material is 16:9 anamorphic so I have been using that and it seems to go ok in architect but will that play on DVD players typically? how will it look on 4:3 screens?

if the project was setup for widescreen then it should be fine. DVD players don't care what aspect ratio it is. A widescreen project will be letterboxed on a 4:3 tv but should look just fine.

Great, thanks again for your reply.
