I am a noob to the whole IPTV scene, so forgive me if this is a dumb question. I am trying to set up a DVR I can access from other devices, and I know the Live Channels app has DVR but it is protected from what I have read and cannot be saved to a separate location for server access. I am also aware Plex has a first party DVR application but I am unable to find information about it working with anything that isn't OTA. So I'd like to know if anyone has a setup that is able to achieve this and how did you do it?
EDIT: I should probably mention that ideally the solution to this would be self-contained on the shield
Plex does only support OTA but there are application that will emulate IPTV to appear as hdhomrun tuner. Look into xTeve, it works very well but you will need to set that up on a computer. I have mine running in a VM and it works very well.
