Ok, it looks like the patch on trac hasn't been accepted yet so I'll do
up the changes this weekend and post a -v2. That'll give me a chance to
expand the comment for getContext which I learned more about as I was
reading through mythVideo.

And... maybe add a blurb about it on the wiki, in the hellomyth
article.  Like I said, I'll try to cram that in this weekend maybe. :-)
