Does anyone else have this problem?  Some titles are horrible jerky and corrupted on Death In Paradise (Series 2 for example).  I normally have Film Mode set to High and Motionflow set to Smooth.  If I turn off Film Mode in the motion processing, the problem goes away.

It doesn't seem to happen on all titles but is shockingly bad on some.  Death in Paradise is only a 1080p signal so it's not 4k or anything.

Is this a known problem?

My TV is a 49-XE9005 running the latest firmware (6.562).
