Tvheadend

I use CD NL via Satellite (SD, with an orange and a grey card: 2 USB readers).
I moved RTL services to the new location on Astra 1 as announced by CD, they are putting all their SD service on one mux. A simple matter of mapping the stream on the other mux to a channel.
Yesterday I noticed that OTA EPG is not refreshed for any of the Dutch channels, the last remaining EPG entries stop on Wednesday July 17, so 1 week after I moved to the "new" mux.

1. Does anyone have OTA EPG still working for CD NL?
2. Also after you moved to 12,515 kHz?
3. How? Alternatives?
4. Anyone with an up to date description how to get xmltv-nl working (just enabling the grabber does not do it for me). When I used Mythtv, I had tv-grab-py-nl working "most of the time." With hts I've been on OTA (til now).

EPG for Freesat (opentv) is working fine, of course.
