One way to do it, is keep it high quality, and then just
play it on your Media Center computer.
The quality is awesome, just as directly from the camera.
My media center pc is connected all digitally, hdmi cables, so the
quality coming from the computer is just amazing. ( Dvi out from video card to hdmi of 1080p TV )
Of course, if you are not running Windows, there are many other options available to get your computer running on your 1080p or 720 p TV.
