Sorry, I do not believe it is just compression artifacts though I admit
the possibility. And all my comments about 1080p have been prefaced
with the qualification that sufficient (not equal) bit rate was available.
At any bit rate and codec there is probably a sweet spot resolution.
But my hope for 1080p was based upon blue laser DVD with maybe 30 GB on
a blu ray or dual layer HD-DVD, using WM9 or AVC. That should be enough
for 1080p and I really hope they use it.
