Using Channels to watch recorded episodes without HDHR

I will be moving temporarily for a few months where I will not be able to use the HDHomeRun tuner and an antenna. I have hundreds of episodes recorded on my hard drive using Channels app.

Can I still watch these episodes on my AppleTV using the Channels app without the HDHR tuner installed? Do I still need to subscribe to the DVR functionality of the Channels app to watch these recorded episodes on my AppleTV?

I know I could simply watch them directly from the hard drive, but I want to have the convenience of simply clicking on them in the Channels app on my AppleTV (like I’m doing now) rather than Airplaying them from my computer.

You can watch them as long as the DVR is subscribed/running. It doesn’t matter if any hdhomerun is available.
