I have a two-day-old Tablo connected via RJ45 to my Internet backbone (no WiFi involved). I have NO external drive. I’m using an attic antenna that my Amazon Fire and TV have used in the past. During installation, Tablo was recognized immediately by the LG Smart TV app and can record/playback some programs. However, this morning, when playing back a program which was still recording, the screen froze and displayed a spinning wait cursor. I had to turn off the TV and start again to return to Tablo. I tried the same recording (CBS Today), and it froze in the same place. I tried another program which was still recording (ABC Good Morning America) and it worked fine.
I have tried to uninstall and reinstall the Tablo TV app but that did not fix the problem.
So far, I’m not impressed by these ongoing issues.
