Oh I forgot one thing...
HDMI!
If it's high-def, you gotta use HDMI! (Technically component cables can handle the weaker 720P HD)
The quick rundown of cable types (if I can remember it correctly):
i = Interlacing (half of the pixes refresh each time, taking turns)
p = Progressive (every pixel refreshes every time) MUCH BETTER!
Video Cables (some include audio):
Coax - Can technically support just about any signal, usually only used to get cable/satellite to your box
Composite - Max of 480i (the good old "Red, White, & Yellow" that comes with every dvd, vcr, cassette tape, and toilet it seems)
S-Video - Max of 480p (requires Red/White audio cable still, seen on some older laptops and dvd players)
Component - Max of 720p/1080i (the good old Red, Green, & Blue...plus of course Red/White for audio, or perhaps digital coax or digital optical if you want to get fancy)
HDMI - At least 1440p (not that we've even seen it yet, so you can say it's quite future proof! it also includes up to 7.1 channel audio within the same cable and some even support ethernet connectivity!)
Audio Cables
Composite - (The Red/White from above) supports stereo audio
Digital Coax - (looks just like composite, but heavier duty and usually orange) supports 5.1 channel audio
Digital Optical - (black jacks with little flap covers in them) supports 7.1 channel audio
HDMI - (looks like a USB connector but slightly wider and with a bevel on the ends) supports 7.1 channel audio
