Santa bought me a Western Digital HD Media Player, which is pretty cool. I'm sure there are other similar solutions out there, but thought for those like me new to moving pictures it seems to be a very simple way to get my new EOS5dmkii 1080 movies into the home entertainment environment.
It's a little black box with 2x USB 2.0 inputs and a HDMI out . You plug in your USB storage device that contains your HD movies (HDD or USB Stick etc) and then plug the HDMI into the tele, button the remote and hey presto... your HD1080 movies on the big screen.
The 5dmkii clips look beautiful on my 42" Panasonic 1080 Plasma, and the part I like is that the clips can just sit with the device and can be played anytime without having to plug in the computer.
It also plays still pics (jpeg, tif, png, bmp and gif); and also music files (mp3 and others).
Not all the bangs and whistles of Apple TV... but 1/2 the price and supports 1080p.
