Unless I have not read the product data right. It looks like adobe did NOT inlcude a multi-angle angle feature to their newest upgrade. And they call this pro-authoring software? I guess I'l stick to Sony's DVDA.
I'm upset as you are with the lack of multi-angle support along with advanced scripting. If Encore would add those two features it really would be a full fledge pro DVD authoring app. My guess is that they don't think a lot of their user base has the need for multi-angle, so it is not at the top of the list. I think if they put it in their lot of users would start using it and be able to offer it to clients. Especially when doing certain types of training DVDs.
So, when I need multi-angle or scripting I use DVD Studio Pro and the whole time wish I was able to do it in Encore. If you design your menus in Photoshop and After Effects the integration in Encore is a real timesaver. I realize that every time I have to use DVD Studio Pro. Personally I think it would be very cool if Encore could import Premiere Pro multi-cam projects as multi-angle tracks!
