Something is strange about the DIY Network "Building Off the Grid" shows.
Not really an issue with Channels DVR as far as I know, but it's a pain to record what I think of as episodes in a Series.
I would think it's a series called "Building Off the Grid", but each individual one (which I think of as a series episode) is considered a special, has it's own SeriesId and tmsId and there's no EpisodeTitle, the series and episode names are in the Title name, i.e. "Building Off the Grid: Hawaiian Hideaway".
If you search for "Building Off the Grid" you see each individual one as a special.
If you set a series pass for one of them it will record all upcoming instances of that Title name, probably because Channels DVR thinks that's the Series name?
As an example, try setting a series pass for the upcoming "Building Off the Grid: Hawaiian Hideaway"-SeriesID:16210205, or any other one. It will record every instance that comes up.
