Maybe the older Tablo is more reliable. There's been some more negative feedback about the 4th gen Tablo on here lately:We record OTA with an older Tablo with a separate HD. It has 2 OTA tuners so can record 2 channels at the same time and uses our WiFi for either watching Live OTA, or any of its recordings on any smart TV on the network. So far it has been pretty good. We haven't come across any streaming channels that we have felt need to record from (yet?).
