It all boils down to what your Television source is, free Over-The-Air (OTA) broadcasts, Basic (unencrypted) cable (no set top box required), a higher cable subscription that requires a set top box, or satellite.
For OTA broadcasts, you need a TV Tuner that accepts a digital (ATSC) signal.
For Basic Cable, you need a tuner that accepts a ClearQAM signal.
For a higher Cable subscription, you could still use a tuner that has a ClearQAM signal, but the signal would have to come from the set top box and I believe the Coaxial output of the set top box is converted from digital to analog. A cablecard solution would probably be better suited.
I don't believe there are TV Tuners for satellite signals.
Thanks for explaining all the acronyms. Just use an antenna with OTA broadcasts. Am leaning towards the Avertv hybrid volar max tx tuner since it has so many high reviews. Just wondering if there is something newer that works better, faster, cheaper, etc.
Following up, ended up getting the Avertv Hybrid Volar Max TV Tuner Kit for Windows and it was pretty easy to install, still figuring out how to use some of the media center since its recording everything but it seems to do what it's supposed to.
