I found something that looks lie a function for replaying:
On the bottom right side there is a Button "show play list" (F3). Starting a disk gives a list that shows all files on the disk. You can select one, delete them also. After deleting all but the main movie remaining, there is a button on the upper right (list options): There you can select "repeat playing all", "repeat playing one only" etc. I tried it several times but this already added feature looks like looping the content but, on my system, never works until now. May by I am doing something wrong? But I think that THIS is the "missing" feature to found not easily.
