Something is wrong with the 6906-kernelmodul or maybe tvheadend.
TVH finds only the same channel-names on different muxes:

TVH setup seems to be fine (SCR and so on).
Verify if mxl85x loaded with mode=2 seems fine too (/sys/module/mxl58x/parameters/mode gives 2).
Any suggestions?
EDIT: seems like the same from here: viewtopic.php?f=176&t=24831&p=53231&hilit=6909+unicable#p53282
