I use a Shield with an HDHomerun and antenna. I have no problems using their "HD" program to watch shows and record them to an external hard drive. I tried out "Live Channels", which also works to view TV (and has a nicer guide), but won't work as a DVR. When I click on a show it says I need an exterrnal drive hooked up to use the DVR. Upon a reset now it just says "This show can't be recorded". I see no place to change settings to tell it where the external drive is. I cleared all its data and rolled back an update but nothing helps. Anyone get this to work?
make sure you are using "network tuner (beta)" as the tuner source and NOT the HDHR androidtv app. The HDHR app requires you to buy a subscription to DVR. The built in tuner source of live channels does let you DVR stuff - it works great on my HDHR Prime
