Need Mac/Iphone help.

So jd, how do you want to do this?

Also: i just bought a 42 inch samsung lcd hdtv. I have an HD cable box from time warner but, not a samsung box. If i get it to the HD channels it will usually only play in 720p and the screen is all shifted and shit. Ive tired adjusting and moving and playing around and i cant figure it out. So its been on 480p on regular cable the past 2 weeks and im about ready to sell it. Its got the hdmi cable and all as well. Im pissed my 1080 p samsung 120hz is looking like shit. Need help. Plz n thnx.
