	Thanks for the quick review, John!

	Aah. Yes. Good point.

	Probably me. The changes in MythTV go well beyond
just libavcodec (to configure, and all the calling code),
so I think the name crept in there as well, and then down
into the lib.

	OK. I will start correcting this. Short is good.

	I wasn't sure if the DVDV stuff allowed multiple
clients (e.g. MythTV does PiP) so I wanted a variable
that could be incremented for each simultaneous client.
