The Hauppauge 950Q arrived today two days ahead of schedule. It works perfectly. Seamless is how I would describe it since it functions exactly as if I'm receiving satellites on the Edision. I actually tried to make the installation more complicated than it was. I tried to look for drivers in a plugin. That was all unnecessary since all I had to do was connect the OTA antenna, select the new Tuner C for OTA, scan for channels and the OTA channels appeared. Video quality is excellent. I tried recording three shows at once (Tuner A, Tuner B, Tuner C OTA) and that also worked perfectly.
The only different operation from using my TV is that subtitles can't be made to appear onscreen when using the Hauppauge. Sometimes I like watching only the video without the audio but with text scrolling. So to do that, I also have the OTA antenna connected directly to the TV and I use the TV subtitle function.
