I assume it’s part of the way the Tablo buffers the live stream when selecting a channel to view, but whenever I switch to a channel in my guide the picture plays back for a few seconds and then the stream suddenly cuts to black and then begins playing back at the exact moment when I tuned into the channel. Sometimes this will happen just once after tuning to the channel, and other times it can happen two or three times in a row. Is this normal behavior for the Tablo, or should I try a different hard drive? Using a Seagate Expansion 500GB. Tablo Firmware 2.2.2.
Is your playback device a Roku by chance?
If so, go to Settings at my.tablotv.com in the Chrome browser on a computer, or the iPad app and uncheck Fast Live TV Startup.
