Well, I do use the double-speed poke. :-)  The code probably isn't
all that impressive either -- I mostly crafted the data format to be
easily processed.

I intended to open source the code, but honestly this is the most
interest that anyone really seemed to show in the player in the
last year!  Before that, I was kinda burnt-out on the project and
never got around to releasing a git tree for the code.

Anyway, I guess it comes down to expectations.  For me, I was
tickled to get recognizable images on the screen synchronized with
the corresponding audio.  Steve and Nick want more, and that's fine.
CoCo will never make a very good TiVo... :-)
