How to watch air broadcasted TV with VLC Player on a Mac I want to watch my air broadcasted TV with VLC Player on a Mac.

I have a standard European TV connection (free air-broadcasted TV), and I would guess I need some sort of USB TV tuner to connect the antenna cable to my Mac.

Can I just buy any USB TV tuner, or do I need to get anything specific?

Could you give me an example of device I need to buy? I'm not asking for suggestions about what to buy, but just an example to define the category.
Do you have any particular reason for needing to use VLC?
If you don't you could try EyeTV as it supports a good range of tuners (mine is a miglia) and has a streaming app for the iPhone / iPad
