I live in Germany and use DVBViewer to watch and record IPTV vie Telekom Entertain. Since friday the 4th I'm getting a heavy amount of artifacts on live tv and recordings and have located the Geforce as source of the problem, because everything is fine with the Intel HD4600.

I'm getting those artifacts on TV-(recordings) from that day on only. Older recordings, albeit recorded with the same software, or BDs/DVDs don't seem to show artifacts, regardless if I use MPC-HC or PowerdDVD14. Temperature is at 32 idle. I Use LAV Filter x64 0.67 (0.66 was used when it started) an tested all Win10 Geforce drivers.

Could it be a hardware or software problem?
