I cant believe there is that much of a difference in DVD players. So far the HK DVD22 has performed above my expectation. Its video and audio quality is stellar. The zoom feature lets you zoom up to 5x on still and motion pictures with great quality. My only gripe is the small remote. The remote has alot of small buttons that are hard to read in low light. It is no big deal because I have a Sony RM3100 comander touchscreen master remote so the HK remote goes in the cabinet with all the rest. Quality and price you cant beat the HK DVD22. I paid around $175.00. It looks cool too, with its silver and blue lights. I highly recomend it.
I think people get lost in conection compatibility. Who cares if its got HDMI if the picture looks like crap. The most important issue is "How does it look and how does it sound?" Everthing else is trivial.
I have a 50" LCD projection HDTV (Sony 50WE655) and tried both the Samsung HD841 and Toshiba SD5790. I was not happy at all with the pic quality (though the Toshiba picture was better), and returned both. Today, I purchased an HK DVD22 ($179 at CC)--finally a DVD player worth keeping! Very good pic quality and digital sound.
