Hi Grimson! Thanks for the quick response. Good point, I just created the same case in their forums: Playback issue with 3D ISOs
Well with "finding an answer" I meant to use the forum search because I doubt that you're the first one that has problems with 3D content, actually I'm pretty sure there was rather big thread about this on the Kodi forums a few weeks back.
Btw. Side By Side and frame packed content are two entirely different things.
