Hi Klaus,

I am using MythTV in Germany with digital cable TV (DVB-C) and EIT data. Technically this works well without problems - there is data available for approx. 23 days in advance (depending on the channels - the private channels have a much shorter range (approx. 7 days)). The EIT data that is far in the future is lacking details that get enriched somewhen later.
But - as Stephen pointed out - the free EIT data always lacks powerful informations like tv series season and episode numbers, "new" informations and so on. But one can work around most of this with using time constraints.

 From the setup of my system I can remember that I had to put in a starting frequency number to kickstart the channel scan. While parts of the other methods did worked as well (e. g. import of a channels.conf), the EIT data didn't worked then!
EIT started to work for me with the real channel scan from within MythTV only, using this starting frequency.
This may be different for different locations or different sources, though. I found this essential piece of information in the file /usr/share/dvb/dvb-c/de-Kabel_BW, that is the appropriate region file for me.

Maybe you already did this, but if not, check the information file that is appropriate for your source/region.

If there is anything else I can help with, feel free to ask me. I can check on my system whatever information is needed (as long as it is running ... as the hardware starts to make problems since a while, but I want to wait for Spectre/Meltdown fixed hardware.... :D :D )

Regards,
