I haven't watched any of his videos - they're not something that interest me, and from the description above it's probably just as well. But I wouldn't want to allow the videos to influence my opinion of him or his music.

ive been told hes an arse

Maybe so (although I'm not quite sure what you mean by that) but I found him just a fairly normal friendly guy and pleasant enough to talk to, like the great majority of folkies are in my experience.
