Am I correct with the assumption that I have to use the media_build drivers?
just update to my 7.0.0 images and they should work (nothing to setup at the addon)
now you have choosen media_build you need to remove the dvb-driver.txt from your download folder and reboot - then you have the normale kernel drivers (where the patch is in)
I have a look why this isn't working.
These scanning issues need to get reported to the Tvh issue tracker, for a lot people these are fixed with 4.1.1943 but I don't know the actual problem. At the moment there is 0 issues at the Tvh tracker about this so it won't get fixed soon I think if nobody reports them. My hardware is fine and everything works like expected so Im not helpful to solve this issue besides update the addon.
I just grabbed it again after your post and all files are there
random anti virus tool problem ?
I made LibreELEC 7.0 installer for NOOBS on raspberry pi 2/3.
we create official noobs images so no need for user-created ones
but tx for you effort 
Did you do any additional steps after install the image?
Go to the dvb drivers addon and activate ljalves drivers (should reboots directly afterwards)
Would be great if you could add support for Terratec Cinergy USB HD S2 (Prod/Vendor-ID: 0ccd:0102).
Is now (hopefully) supported - just update to my 7.0.0 images and they should work (nothing to setup at the addon) - pls test if they do. If you want't to get them to official kernel pls try and report back if this work.
Updated to LibreELEC 7.0.0 (Jarvis)
- added latest Digitial Device drivers (much more up to date then the OE/LE included one) - they compile no idea if they work 
- updated to latest crazycat
- RPi2/3 images added !
- that you have to create the dvb-drivers.txt manually have been fixed I hope
I have posted a bug-report.
Problem identified - I thought we fixed this already, we have a look tx.

Is it possible to add the dddvb drivers from the Crazycat repository?
tx for advice - din't see that TX !!
I add them (if they compile ofc)
Have never receive an activiation email, yet still seem able to post etc. Also have not changed the email address on my account.
you have been activated by admin
Would be great if you could add support for Terratec Cinergy USB HD S2 (Prod/Vendor-ID: 0ccd:0102). In Ubuntu there
I make you a build - I created a patch which should work (if this work I send it upstream that the next kernel has this in).
want to activate the extra drivers my system just restarted..
thats intended - you need to restart to activate an driver (for the cinergy is no driver out there - besides the patch)
and you're correct on ATSC-T...now there are 0 pre-defined muxes listed
nice ... still searching for the problem ... everything looks okay
updated to 4.1.1943 pls have a look (atsc not fixed)
We changed nothing, maybe it was wrong before and now it breaks due an change at Tvh. I investigate.
Please Note:
I have noticed on the forum site in the user profile options there is no button/option to resend an activation e-mail. Is it possible
this could be added to the user account profile page somewhere?
Only possible at the upcoming mybb 2.0 
The 4.1.1931 test build and the 4.0 build from the repo work fine.
service.tvheadend42
could you test if 1933 also work - just to be sure

I'm not sure if this changes anything - but if this is not working this is an Kodi problem. I have now forced to use the "new" samba - nothing more I can do. If this isn't working correctly - the implementation in Kodi isn't that great.
