Live TV with HD Homerun recorders - Closed Caption / Subtitle tutorial?

[mohoelx 12]

Hi. I use HD Homeruns for recording my Live TV directly into Emby. What I am struggling with is the Closed Captions. We don't use them always, but there are times (like on Watson when Shimwell is speaking) that it would be handy to be able to see them. Problem is, I can't seem to get it figured out. Is there a tutorial somewhere on how to set up so that the recorded closed captions can be turned on at a per-program level?
