Which Tv tuner card for my HTPC that will do HD?

A Tv tuner card is literally the last thing to finish off my HTPC and I need a little help picking one out.

I'm not sure what to look for, specs, ports etc. The only thing I want tonmake sure it does is be compatible with HD channels.

Beyond that I'm not sure what to look for.

I'd like to stay under $75 if I can, but can spend more if needed.

I do not need one with a remote as I have an Origen Media remote for my Origen case & display.

Suggestions?

I am very happy with my Hauppauge tuners.

Their tuners are great. Their software is clunky. Go with SageTV or equivalent and you will have it all.

I have two Hauppauge HVR-2250's. They work with Windows 7 MCE, Sage TV and Beyond TV. The 2250 has dual analog tuners and dual digital tuners. You can only use two tuners at a time, though.

2 analog or
2 digital or
1 analog, 1 digital.

I too, recommend Hauppauge.
