Thanks John :)
It would be nice if there was something that could detect the presence of caption files, but I understand that could be really difficult with the different formats. I can pretty much tell if the caption I see is YT's version, or an actual added caption file. It's especially obvious when you've got medical terminology or doctors with heavy accents, what comes out of YT's auto-captioning is hilarious (almost).

>(Just a guess at this time).
