Almost every video that you'd see on a new HD-capable TV is either not HD at all or has too much noise to really look good; the latter is often true of big store displays that split the signal between fifty TVs on a wall.

When you see a Blu-Ray player playing a Blu-Ray disc and plugged directly into a capable TV, I gotta admit, it's really fucking nice. Over-the-air HDTV signals look remarkable, too, even better than standard-def DVD (HDTVs will receive analog and HD broadcasts side-by-side, which makes quick comparisons really easy).

My only complaint is that I can still see weird separation-like effects when an object is moving at a decent speed across the field of view. I haven't figured out if it's due to film being digitally transfered or something, but I get distracted when I see it in an otherwise spectacularly crisp shot.
