but still occasional continuity errors when playing live - 8 errors in about 15 minutes
Run "vcgencmd arbiter set arm_uc 12 0" from ssh and see if it helps (you can add it to autostart.sh to make the setting permanent).
Also overclock the sdram to at least 550 mhz
no problem at all, DVB-S with DVB-Sky960CI running smoothly, no artefacts visible!
Try a 1080i channel, with deinterlacing method set to "MMAL - advanced".
The problem with with kernel 4.9+ and RPi3+DVB dongle is that you can't use advanced deinterlacing on 1080i channels due to frequent artefacts.
With kernel 4.8 (and older) there is no such issue.
I'm pretty sure that the issue is RPi-specific. For whatever reason it simply perform worse with kernels newer than 4.8.
I did some testing on Celeron J1800 board and I don't see any issues with Generic builds with any kernel.
I just tried a kernel 4.11-rc4 build and it is just as bad as 4.9/4.10. Looks like we'll be stuck with kernel 4.8 for a long, long time.
Hey, with the latest MR release, will this bring about the same issues we have as still using same kernel?
Official 8.0.1 RPi2 is still unusable for me. That's why I did a custom 8.0.1 with kernel 4.8.
I can only test the RPi2 builds. No idea what's going on with Generic builds, you will have to test those yourself.
Well how about rpi first generation ?

Any chance of a build for Generic x86_64 ?

What differences for media build and no media build? Which should I try for raspberry 2 and tevii s660 dvbs2 card?
I compiled a Kodi 17.1 (final) builds for RPi2/3. Linux kernel 4.8.13, without and with media_build.

Kodi now defaults to Bob deinterlacing on HD channels (when deinterlace method is set to Auto). If you want to use a higher quality Advanced deinterlacing you'll have to manually select "MMAL-Advanced".
Today i tried the 8.0.0 kernel 4.8.13 with mb.. still conituity counter errors. The build without media_build works fine for me.
This is odd. Probably some media_build driver issue, unrelated to the issue I described in my original post.
On my RPi3 + DVBSky s960 I tested the following:
Official build - 8.0.0 with media_build, kernel 4.9.8 - problematic (as described in original post). Advanced deinterlacing causing video corruption.
8.0.0 without media_build, kernel 4.9.8 - problematic (as described in original post). Advanced deinterlacing causing video corruption.
8.0.0 with media_build, kernel 4.8.13 - no issues. Can use Advanced deinterlacing, no video corruption.
8.0.0 without media_build, kernel 4.8.13 - no issues. Can use Advanced deinterlacing, no video corruption.
Tried updates from post #14 and #22 but it doesn't help.
Did you update VDR/VNSI to the latest versions?

Probably there is same problem with kernel on my box.... Any chance you could compile 905x build for me smp?
Amlogic devices have nothing to do with linux kernel 4.x. They provide their own kernel which is currently based on linux 3.14.
Tried to build with 4.9-rc1 but failed.
linux-01-RPi_support.patch from 8.0.0 seem to be incompatible and it does not build so I have no idea how to proceed.
For what it's worth I tried a 4.9.0 build a while ago and the issue is definitely there.
IMO without media_build should be your first choice. If it does not work try the media_build version.
