That's why I described exactly what's going on in the delete thread
because the watch recordings screen reloads twice.  Once before the 
actual file and database delete and once after.  I wish there was a
way to get rid of this 2nd reload but it is necessary to get the 
free space updated.  Maybe we should just do a query on the freespace
rather than loading the whole recordings list since the backend knows
whether the list needs to be reloaded (ie when the file couldn't be
deleted and needs to show up again on the watch recordings screen).
