My hardware: Rpi3, DVBSky s960 DVB-S2 tuner (connected to the same RPi3).
Software: VDR/VNSI (both frontend and backend are on the same RPi3).
I was using nightly Milhouse builds and this hardware combination worked perfectly fine until build #1215. That build was the first one that used the new 4.9.0 kernel.
I noticed a somewhat rare, intermittent video corruption when watching 1080i h.264 TV channels - usually a flash of green artifacts. Those video artifacts appear once in 5-10 minutes (sometimes more frequent).
That issue is still present in LE 7.95.1 and latest Milhouse builds. It is also present in kernel 4.10-rc Milhouse test builds. Only builds based on the 4.8.x kernel (and older) don't have this issue.
Got exactly same bad experience with my dvb-s card on kszaq amlogic s905x builds. Doesn't matter if I use TVH or VDR getting plenty of artifacts and green screens I was going crazy and start thinking of returning this sat card. Probably there is same problem with kernel on my box.... Any chance you could compile 905x build for me smp?
