Watching TV on your Mac?

Hello,
This is my first post on Mac Forums. I wanted to know if there is any programs to DL so that I can watch TV on my macbook? On my PC I have a program called TVU, and I can watch live tv on it. I am new to the mac world and would like to DL a program to watch TV on my new macbook. If you suggest a program, please let me know where I can DL from. Thanks in advance

You'll need a TV Tuner card or an external device like this one, which is my personal favorite:

Then if you buy their hardware then you'll get their software as part of the purchase:

Similar to TVU for the Mac is Miro.

Oh there is also something called the slingbox which you might want to look into. I have heard it works quite well also.

The EyeTV Hybrid is a great little piece of hardware/software. For $69 you can't beat it: http://eshop.macsales.com/item/ElGato/10020415R/
