TV broken in v7.95.1 and later / artefacts on all channels

Yesterday I've upgraded from 7.90.010 to v7.95.1. Directly the channel startet with the loading image and artefacts. The picture was totally broken. Waiting has not helped. A reboot has also not helped. I switched to several other tv channels and everywhere the same issue. No chance to view TV anymore.

I have downgraded directly and I'm now back to a working system. That was not a "weather" problem.

I'm running tvheadend 4.0 server and tvheadend pvr in this htpc with a digital devices cine s2 card. MB is an zotac atom with nvidia card.

Upgraded to v7.95.2 BETA and still the same bug. Downgraded again

All tvheadend recordings are broken. So it is safe that this is between tv card and tvheadend. It is not a tvheadend client streaming issue. Older recordings are playing fine, everything new that is recorded or views show permanent artefacts. It is not possible to view anything anymore.

This is a clear showstopper for a final release I think. This software is no longer fully usable. Tv does not work at all.

The only question we need to ask here is - what has changed between 7.90.010 to v7.95.1. I guess not the digital devices drivers. The root causing change just need to be rolled back.

Aside the tv card uses ngene18 driver as I know. Per github this driver has not changed for about 2 years or more.

So still broken with 8.0.0. Is there any developer here who can help, please?

Ubuntu Pastebin

Developers - are you there???

Still an issue on 8.2

DVB issue since LE switched to kernel 4.9.x may be a duplicate.
