I have the same issues. I have a Roku Ultra 4670X, currently running 12.5.0 build 4175-46 (current.) I’m using the Tablo 4th gen with firmware 2.2.46. The Tablo TV app (new one) is version 0.8 build 100. The TV is an older Sony Bravia 55 inch.
I have tried both wired and wireless networking on both the Tablo 4th gen and the Roku Ultra, does not fix the issue.
I have replaced the ethernet switch that the devices are using. No fix.
I have factory reset the Tablo 4th gen and the Roku Ultra at least a dozen times. No fix.
I have tested WITH an SD card installed in the Roku Ultra, and without. No difference.
I have uninstalled the Tablo TV app on the Roku Ultra, rebooted the Roku, reinstalled the Tablo TV app. Problem remains.
Every time I do the factory resets on the Tablo, I now perform the “guide” workaround steps using the instructions that Tablo emailed last week. At least the guide looks OK using that workaround.
If I play any 720 or 1080 stream (OTA based) from the Tablo TV 4th gen to the Roku Ultra 4670x, the Tablo TV app will apparently crash after 3 - 3.5 minutes. Very repeatable. Any of the Tablo 4th gen FAST channels don’t crash. Streaming any 480 OTA streams don’t crash.
The SAME Roku Ultra 4670X connected to the same Sony TV works flawlessly with my Legacy 4-Tuner Tablo.
The Tablo 4th Gen streams fine to: A 40 inch Phillips RokuTV, and a 55 inch TCL Roku TV. So the issue is specifically on the hardware in the 4670X. I believe the issue began after Roku rolled out version 12 of Roku OS.
I submitted a ticket. Tablo Support did remote into my 4th gen, said they couldn’t find anything wrong. They suggested using a different streaming+TV device in the bedroom…
My Legacy 4-tuner has been flawless for over 2 years. IMHO the Tablo 4th generation software, specifically for Roku devices, needed more QA time before a public release.
I’d even volunteer to ship my Roku Ultra 4670X to Nuvyyo support (since apparently they don’t have one) if it would help other Tablo 4th gen customers on Roku…
As you can tell, I’ve spent HOURS testing this. Quite frustrating. I like the new UI on the 4th generation Tablo, but I’m losing faith. HD HomeRun and a local Plex server is looking better and better all the time.
