Do the channels on the EIT-based source have their 'useonairguide' flags set?

For EIT to work, the config needs:

i) full DVB multiplex settings with associated set(s) of EIT-enabled channels
ii) an EIT-enabled video source (Use transmitted guide only)
iii) EIT enabled channels on that video source (useonairguide flag)
iv) for EIT scanning to start whenever the system is idle, active EIT
collection must be enabled. Passive EIT collection can occur during
recordings and LiveTV sessions only

Addiing 'channel,eit,siparser' logging to the mythbackend logfile may
also aid in debugging the problem.
