I got a Mitsubishi 57732 DLP last year. Noticed it has Firewire (1394) ports on it. I am very familiar with using Firewire to hook devices like harddrives, DVD burners, and Camcorders to my computers. However, not really sure of the intended use of it with a television. When I first got it, out of curiosity, I hooked my Macintosh to it with no results. Kind of dropped the issue at that point. Recently, I got HD cable and a SA8300HD DVR which also has Firewire. This got me curious again so I started researching. Well, I have seen a lot of posts but most of them seem centered around someone that is familiar with the 'uses' for Firewire in A/V but with problems.
In order to learn more, I would like to ask some questions to see if my current assumptions are correct.
For Firewire (1394) on the TV, is this to allow the video received via the tuner to be output to some type of other device? (DVCR? DVD Recorder? Computer?)
Is it designed as an input to the TV from other devices (See devices above) to allow them to display on the TV?
Is the Firewire port of the SA 8300HD designed as a method to output it's video (tuner? recorded?) to some other device? (TV?, Recording Device?)
Is the Firewire port of the SA 8300HD designed as a method to input other devices video in order to record it on the 8300?
What are the advantages/disadvantages of Firewire vs HDMI?
Any help in enlightening this newbie would be appreciated.
