WMC has gotten broken many times in the past several years due to Win 10 updates. That alone would make me wary of moving away from Win 7. You've got at least 5 more years of ATSC 1.0. Personally, I think moving from WMC to Tivo is just moving from one nearly obsolete platform to another nearly obsolete platform. Amazon Recast is cheaper, easier and far more functional overall. And of course, now there's Tivo's own new streaming dongle integrated with Sling (and hopefully with AirTV for OTA).
