I've been playing around with the client specific rules (series recording) documented in this thread:
I can't get any of them to work yet normal timer recordings work fine. They always come back with "no broadcast found". Yet I have what appears to be a fully populated EPG. I'm running XBMC 13.0 RC1, cmyth 1.9.16, and MythBuntu 0.27 (backend). Below is a debug log excerpt. The chanid listed on the last line is not in the program table of the mythconverg db.
