Certain MKVs Not Playing

I bought Infuse Pro 4 for iOS a few days ago for my iPad Air. Most of my videos (all MKVs) play fine but I’ve found a few that won’t play at all and I simply see the error message “An error occurred loading this content.” I’ve attached a MediaInfo export from two videos: ST6.txt which is one video that WON’T play and STFC.txt that does play.I tried re-ripping the movie but no change. They also play fine in other players (i.e. VLC). The funny thing is that I also have a few box-sets that some movies will play and others won’t! Any ideas?
