I had higher aspirations: I bought three 2-channel ethernet TV tuners and three long distance antennas. I could tune about 35 LA and San Diego channels plus their subchannels. I wanted to be able to record six channels at the same time. The schedule software was excellent, so I picked out a whole bunch of things to record. Windows 7 supported that and made a great DVR. Better than anything the cable or satellite TV people offered. The playback function even had a pretty good "commercial skip" function.
Worked great for a couple of years but then the software upgrades, hardware obsolesence, and rise of online speed and services made it all less useful.
