This is amazing. Between my 3-tuner HDHomeRun Prime and the extra tuner capacity for some channels via TV Everywhere, I probably won't need a 6-tuner HDHomeRun Prime anymore (if it ever comes out).
The only wish I have is the ability to 'upgrade' recordings from TVE to Cable.
Currently, because I live in California, many of my Xfinity channels are 3-hour-delayed west coast feeds. TVE gets me east coast feeds for many channels too, which is awesome because that means I get new episodes sooner.
But this also means that my DVR recordings of new episodes will often be bad 24fps-to-60fps-to-30fps conversions, which have a lot of motion judder, because the TVE channel will have the new episode first.
The HDHomeRun feeds for these channels have the 60fps frame rate, which does a much better job at showing motion in shows produced in 24fps. So if Channels could be configured to re-record the show on the HDHomeRun, I would get the best of both worlds (new episodes 3 hours earlier, plus a higher quality cable recording once it's available).
(Alternatively, Channels could incorporate some sort of detection and mitigation for a 24fps-to-60fps-to-30fps pulldown pattern. Or maybe the cable broadcasters could just start doing a better job encoding their TVE feeds...)
