I use an antenna for "free" TV broadcast channels {no cable or satellite etc}.
So besides applying for the converter box coupons, I just ordered a TV tuner card & a USB stick that will pick up the ATSC {new digital signal}.

Has anyone tried these?

this is what I ordered-
Hauppauge WinTV-HVR-1600 ATSC/Digital/Analog TV Tuner PCI Card
Kworld USB2.0 Tv Tuner Atsc/qam Watch Record Digital HDtv On Pc

thought I'd give them a try and see how they work....

Another idea along with this is to hook up the TV as the computer monitor
or possibly build a second system for the TV/computer setup since I don't want to use & have to move my main pc from my desk....

so I'll wait to test out those cards and see if they do what we want first..
