Blu-Ray is still new and advancing, that is why with some movies depending on the player you have you will not be able to watch the movie unitil you do the firmware upgrade to it. I have a Sony, so if it requires a upgrade I can go the Sony website and download the upgrade and load it into my system. There is so much you can do with a Blu-Ray disk that the features keep advancing and alot of the older blu-ray players need to be upgraded for it. My player is over 1 1/2 years old. I will be getting the new samsung player. You will also notice that your player may take longer to load a blu-ray movie due to the size of info on the disk. Again depending on the player and how old it might be.
As for HDMI, makes a difference if your listnening to Tru surround sound and all is digital and you want the best picture possible. Remember to make sure your TV supports a 1080P set up. You can get a HDMI cheap or you can pay over 150.00 for a Monster Cable HDMI depending on the lenght you need. most use between 3.2 and 7 feet. Some say a 10.00 cable is as good as a 150.00 one, but you get what you pay for. I had one from walmart, and would get a line in the picture. took it back got another one, seemed good. but tried a friends upgraded cable and picture was clear and audio was great. again depends your set up.

ALso Blu-ray will be in Widescreen, not very common to see a Blu-ray movie and it be so called full screen. One of the Better ones is the newest batman movies, The Dark Knight. It is filmed for Imax also and has alot of Full Screen shots. But if you get the movie look on the back of the package. If it shot in aspect ratio of 2:41 or something like that, black bar will on top and bottom. If shot in like 1:85 you will have a full screen effect.
