The only change in that build to dvdplayer is deinterlace related. Do you have deinterlace set to off/auto/on?
Does setting it to off (and then "apply to all videos") have any effect?

Deinterlace was set to auto, changing it to off didn't make a difference.

I started over with the .kodi folder removed, only changed audio output device to analog, expert settings level, deinterlace off and OMXPlayer acceleration disabled. I also changed back the GPU memory in config.txt from 256 to the default 128 (so the only non-default settings in config.txt were sdtv_aspect=3, sdtv_mode=2 and the decode keys). Still the same.

Drop me a line if you want me to test other settings or need more info.

so long,
