Most likely to occur when “switching” from one live channel to another or when rwd/fwd live TV. When it occurs, even returning to the previous channel will give me the error. Most of the time, clicking retry 3-4 times will clear it up. On some rare occasions, that won’t fix it. That said, in very rare occasions I’ve seen it occur while watching live tv.
When playing recordings, I have other issues with the Tablo Gen 4. I’ve recently started getting an “Unknown Error” at the bottom of the screen when I play recorded shows.
Can’t comment about FAST channels because I simply don’t watch them.
I’m taking deep breaths and giving Tablo time to stabilize their new platform (I switched from a Tablo Quad). But in some cases, things are going backwards.
