Can not play select avi and mvk file rpi4

debug log here:](

fresh install osmc on pi4 using raspberry pi imager.

I copied several .mkv files, one .mp4 and one .avi file to the pi via samba network (files play fine in vlc on win11)

Some avi files do not play, some mkv files do not play (others play)

the MediaInfo program returns this for the files that don’t play (it does not seem useful):
Complete name : C:.…\House MD Season 1, 2, 3, 4, 5, 6, 7 & 8 + Extras DVDRip TSV\Season 5\House MD Season 5 Episode 06 - Joy.avi
File size : 350 MiB


Complete name : C:.…\The.Office.US.Complete.Series.+Extras.720p.BrRip.EN-SUB.x264-[MULVAcoded]\Season.5\The.Office.S05E04.Crime.Aid.720p.BrRip.x264-[MULVAcoded].mkv
File size : 183 MiB

I am keen to learn about how to read a log. Can anyone see why I cannot play these files, and perhaps suggest a way to fix the issue?

Thank you,
