I have an uncompressed AVI file with transparency (alpha channel) created in VV4. when I add this file as a graphic or media into DVDA on a menu page it displays the entire "black" rectangle. Is there a way to tell DVDA that the file has an alpha channel so that the "black" background doesn't show?

In VV4 this is simply done by right-clicking on the event, selecting properties, and then chosing the appropriate type of alpha but I don't see anything similar to this in DVDA. I'm probably missing something simple but any help is appreciated. Thanks.
