Another new firmware release for Tablo DUAL HDMI is on the way.
(This release is NOT for network-connected Tablo DVRs.)
This is a second maintenance release intended to address some additional issues seen by early customers.
A notification will pop up in the Tablo interface by tomorrow (Wednesday the 16th of December) but you can check for and process the update immediately by going to SETTINGS > ABOUT > CHECK FOR FIRMWARE UPDATE.
Yep have this issue as well and really annoying. Also the little circle when signal seems to be poor (though im sure its not since in the previous seconds or mins the image is mint) and erroring out while you watch live tv. Those issues and others are starting to wear me out
