Just pointing people to this thread : https://forum.kodi.tv/showthread.php?tid...pid2795399
I've got a large collection of European 1080i25 Blu-ray TV releases ripped losslessly to folders. These are all interlaced releases, even though many of them are of native 1080p25 content, as Blu-ray didn't include support for 1080p25 progressive in the standard (and many broadcasters master to 1080i25 treating 1080p25 as psf)...
Releases encoded MBAFF interleaved fields decode OK, releases encoded as separate interlaced fields (which is less efficient than MBAFF, but was used on earlier H264 encoders) don't play correctly (they are a blocky mess)
(Disabling Hardware acceleration, as expected, both MBAFF and Separate Field 1080i25 rips play using software decode, but the SoC CPU can't cope with CPU decode and deinterlace and it's unwatchable.)
Native 1080p25 content (most drama and documentary) in MBAFF plays watchable OK. Native 1080i25 (entertainment and sport) content in MBAFF decodes OK, but isn't deinterlaced in anything other than a weave as it is covered in combing on motion.
So it seems that early 1080i25 Blu-rays are a no-go, but more recent 1080i25 Blu-rays containing native 1080p25 content (which is most stuff people here buy I suspect) do play OK.
