Hello, I have had both screens.
The regular Da-lite glass beaded screen is not very good for video. It is much to grainy. You will not be happy with it(IMO). The High Power Da-lite screen is glass beaded but uses much smaller beads. It also has a protective coating protecting the beads. If you use mattes or roll the screen up a lot the glass beads on the normal glass beaded screen will wear off quite quickly.
