After reading this thread, I remembered that I will have to do something
related near August this year.  I have a backend at school that my
roomates are using, and I currently have a backend out hear where I am
for the current semester.  I will want to merge both my recording
schedules and the list of already recorded programs from here to there,
just the history - not the actually list of current programs.  I'm not
sure how doable this will be other than manually going through and
pulling the data from mysql and putting it into the right place.
