Hi,
I had the same problem.
Solution: It has nothing to do with the Mediaplayer, I`ve changed my Router and forgot to enable the NTP Ports again for the Himedia.
Enabling the NTP Ports UDP 123 AND TCP 123 solve the problem.
As described before, the Himedia has no RTC and uses the NTP Ports to get the time.
That`s it.
