I have two flat panels, a Samsung 50" DLP and a Samsung 46" LCD, both a couple of years old. Both had lots of advertising that they were 1080P in the store, but a year later, when I went to install my first Blue Ray (Sony PS3), I found out that the only 1080P input source was the Computer VGA socket. HDMI and RGB inputs are limited to 1080i input. Needless to say, I'm rather disappointed in this, and I hope this is not the case with current gear.
Test the turners for over-the-air performance. I purchased an Olevia a couple of years ago based on Consumer Reports recommendation. The turner is very poor - and Olevia is in severe financial trouble.
Reviewers also need to test the turners properly to evaluate over-the-air performance.
