I watch on a 48" Mits from about 12' away, set to 1080i, connected with DVI.
Pretty new to the HD experience. Had VoOm for about 5 months last summer--saw WOW! PQ a few times, and not so WOW. Had cable HD from November to 3/22/05, and didn't see much WOW! on anything.
Haven't had a lot of time to really check a lot since I got VoOming again, but what I have seen so far looks as good as the OTA HD I've been able to catch. The only pixelization I've encountered has been on OTA, and I deliberately tried to catch some fast action sports and movies on VoOm to see if I could spot it there. Now, I admit, I didn't watch the whole game or the whole movie, but over periods of 10-15 minutes, it just wasn't there on my set, at that time.
I'm not sure I can envision what DarryllP describes as "soft putty-like faces". Of course, I had problems understsanding "pixelization", "macro-blocking", and "mosquito noise" when I first started watching, too!
Maybe I'm just a slow-learner, but it sure seems to me that the most educational and productive comparisons might be had if we were all watching the same thing and the same time. PQ judgement will always be subjective, but at least limiting the judgements to the same subject viewed at the same time, would help rule in or rule out a small degree of the subjectivity.
I, for one, would surely appreciate assistance from the more sophisticated and experienced viewers. I'd like to join your ranks someday, but right now I'm just still trying to understand what they are!
Just my 2 cents
