But here's my rule: if I don't understand the technobabble, then most likely I'm not going to notice the difference.
Don't let the technobabble confuse you. Translating it into terms that you can surely understand, if you watched the first five minutes of a movie four ways (as below) you would have no trouble, whatsoever, seeing the difference, and you would rank the four as follows:
- Blu-Ray
- HD television broadcasts
- DVD
- SD television broadcasts
- HD Internet streaming (like Netflix Watch Instantly)
- SD Internet streaming
The difference between 20,000 kbps and 2,600 kpbs is so big that you will absolutely notice the difference. You may not care about picture quality, to let the difference prompt you to make a specific purchase, but you will absolutely notice the difference.
So far everything I've watched via streaming has looked just fine. I don't need everything streamed to be blu-ray quality if it's just a rental or a TV show I want to see. If I need something in blu-ray that badly, I'll just go out and buy the disc.
I feel the same. For example, sitcoms -- who cares about picture quality? We watched them for a while on the dinky little kitchen television, downconverted from HD to analog, and it was no big deal at all. However, with Lost, I wish that it was broadcast in Blu-Ray quality (it isn't). The difference between how HD is broadcast and how HD is presenting on Blu-Ray, is so significant, and exposes so much of the extra care that the producers of Lost have put into filming their program, that I'm almost tempted to wait for the Lost BDs. (However, there's no way that I can keep from the ending being spoiled for me that long!)
I was watching episodes of the original Star Trek series through instant play, and it looked better than I've ever seen.
Garbage in; garbage out -- and with the original Star Trek, garbage picture quality is the best you can hope for, so there really is very little difference between the various option.
Note that they have remastered the original Star Trek, from the original film, onto Blu-Ray. It does make a difference but I don't believe it makes enough of a difference to force myself to rewatch all that badly-acted, tire, worn-out programming.
When I watched the Harry Potter livecast, which used the streaming version, it looked just as good as the blu-ray. Even my HD-crazed friends were impressed with the quality.
They can push the quality...that's one of the frustrating things about this: They can actually change picture quality on-the-fly, now, without you really having a choice.
