I think Tony hit the nail on the head, because I looked back in this thread ,and it appears you just switched from standard TV to HD TV viewing. Since the resolution of 1080p is quite a few magntudes higher than standard Tv, flaws in stuff that was overlooked are now real apparent.
For maximum clarity, copies of video material must be of the highest levels or else there will be flaws visible; flaws like blurr, or less focus, etc.
How do other video sources look on the new TV, and have you upgraded to an HD signal from your cable provider? I ask this because that is what is needed to view TV programs in HD. Having the HD TV is one part; the other part is HD source material. I know too many people who buy an HD TV and stay with standard broadcast signal. Basically, they “don’t get it” and they rationalize by telling me “it’s not that bad”. How do they know, they are not comparing it to true HD?
