I have two Nvidia Shields and a Mi Box running Channels.
The Mi Box seems to have issues with Channels. First off, it's not nearly as responsive when trying to jump forward / back in a recording. It will seem to go non-responsive for 3-5 seconds when trying to jump past commercials.
Also, I don't use it every day, so many times I turn it on to watch TV and Channels doesn't know where the DVR server is and I have to manually enter my network IP address.
I never have these issues with the Shields.
Any idea what's going on? Is the Mi Box just not a good enough piece of hardware to run Channels reliably?
