From their website it states that they'

"gives your AVM all the functionality of the AVM 50"

Which I believe has the same video processing as the D2, this is a very good video processor and offers scaling to 1080p/24,50,60 (some others as well, I'm going from memory) and offers vertical shift for use with anamorphic lenses as well as incredibly stable HDMI switching.

To my knowledge, the audio sections remain completely unchanged, it is just a video processor/HDMI switcher upgrade. FWIW I have a lot of experience with this processor, and the fact that it work very well and is so well integrated into the pre/pro makes it a HUGE convenience!
