I don't know why Stephen's Previously Recorded list has been truncated. 
Mine goes back to Jan 2005, although there have been problems caused, I 
think, by importing via MythArchive from other boxes.  recordedid  is 
box-specific - and ISTR that Stephen had a fix for that.

The Previously Recorded system was reworked just over a year ago, Ticket 
#13135, but perhaps only in Master?
