I'm considering purchasing a peripheral, HDHomeRun, that connects to the coaxial running from the wall and streams the feed to my MBP over WiFi. However, I'm having a difficult time figuring out what channels I should expect to receive with a direct connection to the coaxial and if they'll be HD. When I check what channels I'll get via cable using the "What channels will I receive?" link on HDHomeRun's homepage (http://www.silicondust.com/hdhomerun/lineup_web/US:92656#lineup_2156083), it lists about 70 QAM channels. However, most are duplicates or throwaways. It is mainly the 3 major networks and PBS that is of interest--all in HD. Cox Cable's list of available QAM channels looks much like HDHomeRun's list: http://ww2.cox.com/wcm/en/residential/datasheet/orangecounty/QAM-OC_3.2010.pdf However, when I connect the coaxial cable running from the wall of my home directly into a TV (without the set-top box), I get considerably more channels; I get the basic cable portion of my digital TV subscription, which means there's the major networks, 24/7 cable news channels, etc. 1) So when I plug the coaxial cable into the HDHomeRun, which set of channels should I expect to receive: the QAM set listed by SiliconDust's channel lineup and Cox Cable's QAM pdf or the more expansive lineup I get with a TV directly connected to the coaxial? 2) And a related issue. Perhaps key to understanding this discrepancy: are the basic cable channels one gets via direct connection to a coaxial cable synonymous with QAM channels? Or are these 2 distinctly different things? 3) Or is the difference in the channel lineups because the first set of channel data (HDHomeRun & Cox's) presents what you would get if you connected the QAM tuner (HDHomeRun) directly to the coaxial without even a basic cable subscription? But if you had at least a basic cable subscription you should expect to receive the same channels over this QAM tuner peripheral as you would when connecting a TV directly to the coaxial? Thank you for any help.
