I have a background video that I want to use for my DVD menu. I want some menu buttons to appear over the video at a time point during the video. How can I accomplish this? I made the buttons in photoshop, and they always have a black background, even when I set the background to transparent in photo shop. So, I have 2 problems. I'm new to Encore, and I've been trying to figure this out for way too long. Help!
