We had a Tablo dual hdmi unit running with four Roku Express (2022 version) devices. All devices are conncted via wired gigabit network. The setup was designed to avoid the smart tvs. The Tablo provides tuners and OVA recordings throughout the house.
For the first few months, the system worked as planned. The Roku would expand the video from Tablo. Then Roku began updating the devices from 2.x.x to 3.0.0. At that point, the video went from smooth and clear to jumpy and pixelated. We knew the update was the issue when a unit that had the old os was explicitly updated. The video went from great to broken up as with the others.
Tablo claims no knowledge of the problem. However, they don’t report any testing with this setup. What they do say is that if the problem is caused by Roku, then they must do the fix - good luck with that!
Has anyone else seen this issue with the Roku 3.0 release?
