Whats the difference between a PS3 DVD Component Cable and a PS3 HDMI Cable. Which one increases the quality of the picture and makes everything better.

These are the two:

This one or PlayStation 3 Component Cable Powerwave OR PlayStation 3 HDMI Cable Powerwave. They both look different but seem to do the same thing, which one should I get.

I heard it is more fun and challenging on hard mode but how much more challenging is it than normal mode. Do you have to be a hardcore gamer to try first time anyway, I thought mhf2 was not hard at all so... How easy can normal mode be anyway?

I'm going to England and the US from Aus and I'm going to be on the plane a lot. Are these good choices?
