The NBC App for Android has all the NBCU channels, such as MSNBC, USA, E! Network, etc. It supports deep links and is reliable for the tuner. However, the app sometimes has a popup banner that overlays on the video and can obscure recordings.
This banner has been discussed here (source of above picture): ADBTuner: A "channel tuning" application for networked Google TV / Android TV devices - #295 by krazijoe?
My use case was to record MSNBC occasionally. So I did not have to look out for the banner, started using the NBC News APP. So far, I have not seen the banner.
