I've had mine for about a year. Works good.
The ATI card has two tuners one for analog( NTSC) and one for digital (ATSC).
Fry's has a 30 day return policy.
I'm using a 19" monitor. When TVs first came out in the 1940s Tv were only 12".
More info about your PC Do you have an ATI video card???
It will work nVida but you have to play around. I got fedup and just got a ATI video card. The current software is good. How fast is your PC, should be 2ghz or faster. You didn't give a lot of info about it.
How far are you from the broadcast antennas???? You do need a good signal! Digital tends to be all or nothing!
Here is a link that I found helpfull, It was started in 2002 but has a lot of info, skip to the last page and go forward. John

Does anyone use the ATI HDTV All-in-Wonder? I'm thinking about getting it has my first HDTV. My monitor is a 19" 1600x1200. It can't show all of 1080i, but at 19" it wouldn't matter. I think it would be worth it even if the HDTV looks only as good as DVD.
Is a there a place where can buy the ATI HDTV All-in-Wonder with a good return policy incase I'm not able to receive good OTA HDTV channels? I think I read on amazon.com that I could only get an 80% refund if it doesn't work.
One problem I might come into is that I already have a SDTV tuner in my pc that I want to keep. I don't know if I have a free slot for another tuner card and I might need a larger power supply.
I know 19" seems too small to bother with HDTV, but I'm the only person who will be watching it and I sit about 2 feet away from the monitor.
