The macroblocking issue that I get from HD over sat is really sickening. Hey, I love my HD, I just hate when the "suspension of reality" has to end so abruptly when the screen breaks up into squares. This is something that a physical disk, and hopefully less compression is expexted to fix...
I expect even the common man with a cable or sat HD connection sees and notices. We call it, allong with reduced res: "HDlite"
