sorry for the late reply.
today i have tried a few things again.
i can play the file, if it is locally stored on the sdcard with this command:
/usr/bin/omxplayer -ohdmi -r --no-keys -l00:00:00 Film.mp4
seems to be the same command, when trying it via an orbiter.
i can copy the file from /home/public/data/... to the raspberry.
This is the output starting the film with the same command from the network source not locally:
/usr/bin/omxplayer -ohdmi -r --no-keys -l00:00:00 /home/public/data/videos/0\,00\ TB\ \(sda1\)\ ST2000DM001-1CH\ \[31\]/Film.mp4

have a nice day ;)
Some times it starts to play for 1 or 2 seconds but then it stops.
This is a part of the logfile /var/log/pluto/205_OMX_Player.log

i unplugged another working mediadirector and put the networkcable into the raspberry.
so normally it cannot be the cable or does this confuse the system somehow?
If You need any further information, log or if i can do something else, i would be glad to help!
