BDMV Playback not working on Zidoo UHD3000 with FW 6.4.62(G)

In previous FW versions Zidoo was well able to play Video´s from BDMV folder Structures (BD- and UHD-BDMV´s via SMB fron NAS). After upgrading my UHD3000 to the latest FW 6.4.62(G) and ZDMC 20.1 i had to realize that this is not working anymore.

First i assumed the problem comes from ZDMC. Later i realized that the same problem appears when you try to play back directly from the Main Menue / File manager:
Message appears: 1) Play 2) Menue 3) Poster 4) open folder
...but nothing happen when you hit play. Screen goes black and returns to the menue after a while.

Can anybody confirm my issues? Is there a solution for this problem??

 

@ the UHD3000 owners: Can anybody confirm if BDMV playback is working on your device?
Thank you very much in advance for your support!
