5-tap horizontal and 3-tap vertical video filtering
As DVD becomes more commonplace on new systems, these video acceleration features become increasingly important, so it's important to understand them.
The DVD motion compensation is a performance feature that allows a significant drop in system requirements (PII 266 without dropping any frames). The TNT2 didn't have this, making the GeForce better in terms of DVD.
DVD sub-picture alpha blending is a quality feature supported by the TNT2 and the GeForce (as well as the Rage 128, S3's Savage series and the TNT). You know all of those menus you click on for navigation in a DVD? Without sub-picture blending these menus would be dithered, crosshatched and downright ugly.
