I can't vouch for it, but it's called 720P.
I am led to believe crts can't do P at all.
Don't know.
The difference seems to be with motion.
I can tell no difference without motion, and 1080i setting may be cleaner with no motion.
I have used some settings others might consider sacreligious, which may have some effect.
It's a fine point, and may have to do with the way the disc is processed, but it does seem to make a difference with really sharp pictures and motion.
Re component access:
The arbitrary denial of services and quality already paid for will bite distribution companies once again.
Bluray discs that can't be played at all, will certainly be secure, as were every macro vhs tape I ever rented, returned and got a refund for.
The worst I ever saw was The Time Machine, which strobed and flickered like a japanese cartoon.
Big piracy problem with forgotten 1962 films?
Netflix told me the worst they saw was on sony decks with sony blurays.
Seems sony media is incompatible with sony hardware.

I predict a public reaction to anti-copy practice of total indifference to ALL copying, similar to ongoing political reactions to other abuse of law.
The nine year old girl fined and prosecuted for piracy isn't winning hearts and minds.
A violent swing in the other direction is coming.
So predictable.
