yeah, that's on my todo list...  the style sheet stuff on the whole
thing needs to be reworked.  I just haven't had much time out of work to
code, and recently realized that I'm running low on disk space, so I
needed to push up the priority on my svcd exporter for myth.

I'm happy to take a look at it - anything to save me a bit of work.  :)

currently, the Program object in mythweb is designed (though not fully
implemented) to get ALL info about a recording, both from the database
and from mythbackend, so whichever ends up working is best.  The program
guide currently only grabs info from the database (thus, doesn't check
for resolved conflicts, etc), but if I query the backend for info, it
should return everything pertinent about the programs, including whether
or not they've been suppressed, etc.
