Simple One Video Channel Example?

I’m looking for a simple example of a channel with one video (exactly the same as a DIrect Publisher channel with one TV Series video). I just need to modify the code slightly to account for the M3U8 feed not always being available. Anyone know of where I can start with something like this?

I would start with the Multi-Live Channel, https://github.com/rokudev/multi-live-channel. Modify the components/Config.brs file to contain your one feed, then make whatever modifications you need from there.
