Blu-ray Discs are able to hold 1080p HD content, and most movies released on Blu-ray Disc produce a full 1080p HD picture when the player is connected to a 1080p HDTV via an HDMI cable. The Blu-ray Disc video specification allows encoding of 1080p24, 1080i50 and 1080i60. Generally this type of video runs at up to 40 megabits per second, compared to the 3.5 megabits per second for conventional standard definition TV's[12]
Thanks MegaCool for clearing this up but i will try to be more specific.
@xterm i think you own a PS3 that has a built-in BD player at 2x read speed. Technically translates to 72 Megabits/sec or 9 Megabytes/sec (so forget about the
up to 40 megabits/sec), this is more than enough for Full HD 1080p24/60 quality movies.
I watch my BD movies on a 46 inch screen and i can tell the difference between 1080p and 720p. YouTube's compression is bad compared to BD but efficient.
What i want to say is if you(anyone) cant tell the difference between 1080p and 720p videos(not games) and dont own an HDTV that is larger than 40". Then dont bother watching a video or movie at 1080p resolution. I know a lot of people who want to watch 1080p videos so that they can show-off about it.
Perform a blind test on a 32" HDTV and use the same video but at different resolution (1080p and 720p), i advice you to download it from the PlayStation Store because it usually offers the 2 resolutions .
