I'm looking for suggestions on calibrating my TV. For the following devices:

Xbox 360 on Component *soon to be HDMI next month* (I can use the Halo 3 one that comes on the LE assuming its also on the Legendary edition as well.)

Wii on Component (I plan on using the same settings as the 360)

PS3 on HDMI (I can use the Spiderman Blu-Ray calibrator)

Now I'm wondering if I should use the calibrators above or if I should just go out and buy a DVD? Is there any free calibrators online?

Also I'm having a lot of screen tearing on the 360 is this something with the games and something that can be fixed with a calibration?
