My Initial Stupid Assessment of the new HD...
HGTVHD and StarzHD: look pretty good!. Supposedly, all the material on HGTVHD will be HD but there will be gobs of repeats. StarzHD looks as good as it did while on VOOM DBS...just hope they have a more robust HD library than they did a year ago (should since they can borrow all the material shown on the now defunct EncoreHD).
NFLHD: is the same crappy/fuzzy 4:3 that was on VOOM DBS. I'm not expecting much from this channel until football season, if ever.
NGHD: so far they have shown a combination of 4:3, 16x9 zoom/crop, and stretch-o-vision...not a great preview up to this point.
