Thanks for all of the suggestions in this thread. I still haven’t pulled the trigger for the Quad yet.
I saw in the TABLO RIPPER App that choosing which Tablo to connect to is easy. I didn’t know if the Roku Tablo Channel would work the same way.
I have been managing scheduling conflicts both morning and night every day with the Tablo Dual Lite, and have missed the opportunity to record some episodes of old TV shows I like. Scheduling movies is almost impossible, because of the conflicts. I intend to use the Quad for just TV series, which hopefully will reduce conflicts. Then I could use the Dual for just recording movies.
Next step is building a cheapo PLEX server, so that I can share OTA content with my kids around the country who have me connected to their PLEX servers.
Your replies and suggestions have all been appreciated. I feel good about buying the 2nd Tablo.
