Just got my Tablo 2-tuner recently in the hopes that I could use it as a bridge between my antenna and my tuner-less Vizio SmartCast TV, but sadly I've had nothing but frustration using it. I think it boils down to the fact that I live in a valley and have pretty sub-par signal from most stations, but I can't seem to get the Chromecast functionality to work consistently.
The OTA channels in my area do this weird thing that when a bus or truck drives by, the signal will get interfered with. My old TV with a built-in tuner would show a scrambled/mangled signal for a split second, then happily carry on when the bus is gone a second later. However with my Tablo, I'll tune into a station and it will initially cast fine to a Chromecast device. But when the Tablo loses signal for the split second, the stream doesn't show the garbled signal; instead it pauses and looks like it's buffering. Unfortunately it never stops buffering at this point, so I have to tune to a different channel to get it un-stuck. When I tune back to the original channel, the Tablo stream time-warps and reverts back to the time when I first tuned to the station. Tapping "Live" just goes right back to the start again. If I stop casting, sometimes the video stream on my phone will actually be live, but re-casting it to the Chromecast goes right back to the beginning again. Gah!
Along those lines, I've noticed that the time-bar when Chromecasting consistently shows 0:00 as the time, with no progress bar nor "live" button. Tapping the +30/-20 buttons just revert it right back to the beginning too.
Any ideas? I got it in the hopes that it would do OTA->Chromecast, but I've had nothing but headaches since setting it up
