Need PAL/NTSC tv tuner

I can't seem to find one that has everything I need.
I just bought a new laptop (ASUS M50VM-b1), and I study in the UK, but from Canada.
So I need a tv tuner that can pick up pal and NTSC.
But not only that, it would be nice if I could hook up a console to my laptop and use the screen as a tv screen (be it a ps3 or a wii).
so I figured a tv tuner would be able to do that, one with component input (red yellow white or wtv colours its meant to be)
S-video would also be useful.
And I would assume it would need a coaxial input for cable tv?
All to be hooked up by USB or esata or FireWire. Those are the ports i have.

So basically need an external device that will allow me to watch tv globally as well as hook up a gaming console to (however that's possible).

Any help or info would be appreciated.

Thanks!!

I actually looked at aver before I posted but for some reason I didnt see what I wanted to see.
The avertv ultra USB is perfect... Almost.
It will play consoles and worldwide analogue.
It should do.
Thanks again
