@ TwoMany
Thanks for the links. I had/have looked at the Roamio. The monthly fee discouraged that.
The Channel Master seems to be the way to go if buying new.

The Hauppauge is well received from what I'm reading. We don't have Media Center software though. Our systems are getting a bit aged and slow for some of the new applications. I can't even watch some of the videos you post without buffering and our isp doesn't seem inclined to upgrade their systems. They sell me a 1.5mb package that speedtests around .9 or 1 mb most of the time. A call to them about it gets me a reply of "we sell the service at up-to 1.5 speeds and what you get is within our perimeters". My standard reply is if I send 2/3 of the monthly bill will it be in "primeter" and acceptable?
Reading several,several hours on forum boards I still can't determine if I could take an old tivo (with an ATSC tuner) and plug my antenna into it and record OTA signals manually without their service. Some say yes, most say no. And then there are the debates about the ethical. Are you stealing from tivo? Endless posts about the ability to hack the box and software. . . . .blah blah blah.
Still looking for a simple way to record free air without paying $2-300.
