I'm pretty sure that the backend can only run one grabber
automatically per video source (although this might have changed
recently). As you need to run two grabbers for your single video
source (that contains the channels served by both _eu_epgdata and
_ch_search) you will likely need to run one or both XMLTV grabbers
manually and import the data through mythfilldatabase.

You should be able to tune your analog channels even if there are no
listings available. Are you sure you have the correct frequency
information configured for the SSF channel? Are you sure all channels
are configured on a single video source in mythtv-setup?
