I get most of my TV programming OTA with an antenna on the roof.
Once you get used to a digital signal it's hard to go back.
There's a satellite receiver, VCR and outdoor camera mixed in with the=20
antenna signal
and shared with all the TV's in the house with a RF remote control.

If you can get a tuner like=20
(http://www.hauppauge.com/site/products/data_hvr950q.html) for < $100
why can't someone like Ramsey come out with a consumer grade modulator=20
for ATSC.

What's the future of whole house video distribution=20
(http://www.smarthome.com/images/vidcabl3.gif)
when manufacturers start dropping the NTSC tuner?


thanks
