I have a plasma 50” (Philips) TV with input from Sat receiver, DVD with progressive scan, HD external antenna. The DVD progressive at 1080i is by far the best picture I have. The ADS HDTV UpConverter II - Video Scaler claims to automatically convert your standard definition video signals into progressive scan 720p, 1080i and other HDTV resolutions. Display video from DVD Players, VCR's, Satellite TV, Cable TV, Game Machines or any video source in the highest resolution your HDTV was designed to deliver. But for MSRP of $400.00 does it do anything?
