I have - and enjoy - the HDMI Duo & subscribe to the guide.
No serious complaints, but one convenience I do miss from the cable system we previously had (FiOS) is the ability to find & set shows to record, delete recordings, adjust settings, etc. while a smaller display box continues to play the audio & video of whatever was being watched (live or a recording) on the full screen prior to having decided to also manage recordings.
I thought I could effectively do the same thing by downloading & using the Android app to manage recordings while continuing to watch my program on the “big” screen . . . until I figured out the app doesn"t work with the HDMI Duo. I suppose there’s a good tech reason for why the app can’t/shouldn’t playback video programs or recordings, but why not allow the app to work with the HDMI Duo just for using the guide, managing recordings, or even as a more effective remote control?
In the 1st place, I think Tablo really should be more up front about the app not working with the HDMI Duo. But if the reason it doesn’t because there’s some problem with using the app to view programs from the HDMI Duo on a smartphone, why not at least let the app function with the HDMI Duo for non-play/playback purposes & describe it as a feature?
