Tvheadend

I'm running latest git master, using TBS cards, which were working before (a few weeks ago).
I found that I was unable to view channels (XBMC reporting no input) so I thought I'd reset the config and do a full rescan.
All the service have been listed OK, but when I press the "Map DVB services to channels" nothing seems to happen.

Any suggestions?

Logs saying "No input detected" - yet it's found all the services OK?
