where i live theres no HD over the air so I have to use a satellite or Cable connection. Itstill not possible to view HD on my system without a setup box?

That is correct.  OTA or via Firewire from a set-top box are your only options currently.

Look for this to potentially change with the release of Vista and its support for Cablecard technology.

My new Westinghouse 32" lcd hdtv gets a few hd channels with no box, direct cable connection to it. Is there a tv tuner card that can do the same thing?

Depends. Most Westinghouse HDTV's support unencrypted QAM tuning, which Media Center doesn't (and can't).

It's ATSC Tuner is "QAM Capable" so it can tune Unencrypted Digital Cable.  There are a couple of ATSC (HDTV) tuners that can tune QAM just like your TV, but only with the software provided with the tuner by the card maker.  The DViCO FusionHDTV5 Gold series tuners will tune QAM as will the MyHD 130 tuner.  But they work with their own software only when tuning QAM.  MCE 2005 doesn't support QAM tuning at all (as stated above)...

Ahh ok, Thanks for your help guys, I didnt inroduce myself this morning as I was late for work.
So I just build my first HTPC but about my 10th computer build. Gigabyte 8I945PL-G motherboard, 2.8 Pent D 920 Oced to 3.2, 1 gig OCZ ram. NEC dvd Burner. 2 Segate sata drives one 80 and one 160. Roswill power supply. Cheapo Sylvania 5.1 speaker system.(being replaced this week), and a Westinghouse LTV-32w6 HD.
Well I am sure I will have a bunch of questions for you guys in the future. so thanks in advance.
