I have a problem with ISO files sometimes they will lock up at about 10 seconds into the video. I have started to let the backdrop info load a couple images first before I click to watch it and this seems to have helped. When all else fails I go to Preview mode and can play it from there.
This is not a menu isse either as some of the movies that lock up do not have menus and they play justr fine on my WD live plus
