No, it's not neccessary. You have to look what (if any) data is 
broadcasted. dvbsnoop -nph -n 10 0x12 while tuned to each multiplex 
should clarify if EIT data is transmitted.

You're expecting somthing impossible. The channels.conf doesn't contain 
neither the original network id nor the transport id.

I would think that your cable provider doesn't transmit any guide data 
(according to the DVB specs he should at least transmit now/next data).
