Now I'm really confused. Is High Definition defined by what you see? Or, is it defined by the Advanced Television Standards Committee?

Can someone post sample photos of the difference in PQ?
Look here:

Maybe this can help. I'm not sure how the test was conducted and how current the information is. Capturing the pictures must have been a tedious process.

My analysis -- The number of effective pixels is the smaller part of the problem. When there is frame to frame motion, those compression induced macroblocks are what's really ruining the image. MPEG compression works on both the space and time.

I recently visited the local tech store and took an up-close look at BlueRay. I couldn't see a patchwork of macroblocks but the image was still not crystal clear. There was a slight smearing effect that that shimmered over the image. I'm being extremely critical here but it looked much better than anything I've seen on satellite.
