Noggin, can you try and go into OSD Video settings while DVD ISO is playing and disable de-interlacing completely and save as default ?
Are you getting ff-mpeg2 decoding of these DVD ?
Checked.
When playing a 576/50i DVD ISO I get dc:ff-mpeg2video.
When I disable deinterlacing on native interlaced content I get what looks like full intra-frame combing, but no motion judder (but obviously terrible picture quality) - though with some semblance of 50Hz motion (It's like a worse version of the old deinterlacing bug the Pi had on MMAL advanced). With deinterlacing in Auto, I get the motion judder I mentioned above sporadically. It doesn't appear to be regular.
When I watch native 25p content I don't get motion judder in either mode (and obviously no combing as there is no intra-frame motion on properly transferred 25p content) but with Auto deinterlacing enabled (or forced On) it appears to be far worse in lip-sync terms.
I'm wondering how optimised ffmpeg is for ARMv7 or CortexA9.
Low bitrate 720p HEVC Software decoding seems to work Ok in brief testing I've done, so maybe it is optimised in ffmpeg 2.8.4
I really don't know enough about Software decoding in Kodi to tell you the truth.
