Best HD TV Card for PC?

[Erasmus]

What's the best HD TV Card for a PC?
I've got a Quad-Core PC, a good TV signal and a blooming great big monitor which I'd like to watch TV on.
Are there any things I need to watch out for (will they all work with N.Z. HD transmissions for instance?)
Are there any advantages in getting an internal card over a USB stick?

I purchased on of Pinnacle's 73E Nano USB Digital Terrestrial tuners from DSE. Seems to need a external UHF arial as the tiny one that comes with it is only usefull if I take the laptop outside and put the arial on the house spouting (arial has a magnetic base) http://www.dse.co.nz/dse.shop/4912b603003f9434273fc0a87f3b0656/Product/View/XH9725

The picture is excellent and I get all the terrestrial channels. Great for playback on the laptop using VLC Media Player. This is better than the software on the install disk for playback as it has a drag time bar on the player. Good for quikd fast forwarding etc.

The editing software doesn't work ... can't figure out why. Maybe because the capture format is different to other countries. It will only capture in "Native format" of TS files. No MPEG-2 or DIVX. Anyone who can help me there??

Apart from that I am quite impressed.
