[mythtv] format of: QUERY_RECORDINGS Delete

[Chris Petersen]

finally found a few spare moments to poke around at mythweb again, and
figured I'd tackle the "recordings" page (the one I dislike the most
because it has some html in it that breaks gecko - or finds one of its
bugs, anyway, and sometimes renders the page funny).

Anyway, I've gotten to the point where all program data is loaded, in a
backend query that asks "QUERY_RECORDINGS Delete", but I don't know all
of the fields that this returns (some of them are obvious, others are
just numbers).

For the sake of good (self-documenting) code, I'd like to document what
each of these fields contains.  Could one of the authors point me to
somewhere that this is documented?

Thanks,

Chris
