But there are different "levels" of being able to play 1080p (or 1080i or 720p or even 480i etc..).

Quality of the end result (moving pictures) can vary greatly, depending upon the algorithms and horsepower applied to the problem.

I used to think, wow it can do 1080p, that's as good as it gets. Except it isn't (always).

Over the past two years, I've progressed here from Wow! at seeing O.T.A. DTV for the first time, to noticing jaggies, to getting rid of the jaggies, to noticing certain kinds of motion blur, to eliminating those, to noticing blocky shadows, to smoothing those etc..

Each evolution took a new level of hardware and playback algorithms.

I think it all looks rather nice here now, watching the World Cup Finals. But I'm sure it's really rubbish, and I just don't realize it yet.
