From a video processing standpoint, the Algolith DragonFly is a great de-interlacer/scaler. It has many de-interlacing features and ultimately resolves a near optimal picture. Functionally, however, this scaler still has a ways to go to meet the level of features that we expect from such products. High-end projector owners (1080p) will like many of the features on this processor, and although it may not do everything they want from a feature standpoint, it can do a lot of things other scalers are incapable of performing.
