Seems that I have the same issue. When I try to start a DVD-copy from Kodi with wrapper turned on (not *.iso, but a folder, which contains a video_ts folder with *.vob, *.ifo etc.) by pressing menu button on remote control on this FOLDER and choosing play function, it starts HMP but then there's a message: "video problem" with "confirm" button below the message. When I press this button, it goes back to Kodi and nothing happens after.
When (in Kodi) I go in this FOLDER and start just one *.vob FILE it plays well in HMP.
When I start the same FOLDER to play in HMP (not from Kodi through wrapper), it plays fine also.
