What is the difference between 1080p & 1080p 24hz?
I just got the Memorex blu-ray player and played around with the setup menus. Under "video" then "resolutions", it lists from 480i to 1080p and the last option is 1080p24hz.
My vizio's HDMI connection shows that it is displaying 1080p when I turn on the player. When I selected 1080p24hz, the video disappeared. I couldn't figure out what happened to the display so I unplugged the player and the video came back, but the player's resolution is back to 1080p.
So my question is: What's the difference between 1080p and 1080p24hz?

Your TV probable does not support 1080p24, which is the exact resolution and refresh rate of all HD DVD's and Blu Ray discs. Even SD discs are encoded at 480p24.
Unfortunately, USA TV broadcasts are all done at 60Hz. If your TV or display will support 24 frames per second, then there would be no manipulation of the original encoded content of SD and HD/BD discs. If your TV does not support 24 frames per second, then all your DVD's will convert their original 24 frames per second to 60Hz so that your TV can display the signal.
If you don't like your video to be manipulated, you do like your video image to appear as clean as possible, then you really need a TV that supports 24 frames per second.
Good luck,
George

thanks GizmoDVD. So am I losing anything by not being able to play the movie the way it is intended?
As a followup question, why would they make HD TVs that use a refresh rate different than (according to bub) all DVDs and HD discs?

Most HDTVs now sold allow 24fps mode.

My LG is a bit odd, because it's NOT 1080p capable, but at the same time does accept 1080p/24 signals from my PS3.
The reason I never leave that setting on is because some - not all - BDs have vertical aliasing and shimmering on specific surfaces and edges, depending on the disc. Spider-Man 3 is full of them, Independence Day is not, and so on.
