Software / Firmware is absolute junk. Worse I have not seen so far.

First the good:
The unit will play a lot of different formats, including all types of ISO files. I have not found any file that the device could not play.
It is also extremely quiet and comfortable and the remote control unit can be operated well.

Now the bad:
A built-in 2TB HDD is formatted with only 2MB, only after I formatted the device to PC with NTFS, the device has detected and linked to full size. It copied data were gone after the next reboot, and the drive was formatted with UTFS, which is not readable from the PC. About 150GB irretrievable data simply gone. Have a few after DTEN copied to the disk. After off / eunschalten also gone. Internal built-in hard disk completely unusable.
While I copied over the network data to disk, the device is in sleep state, which left garbage on the internal hard drive and utter ignorance, which file is OK and what is not answered.
These are 3 of the 15 problems with the software. There are certainly a few more that stand only with time.

Conclusion:
Not Buying the equipment. It would give you only create problems. The whole thing goes so far that I have considered whether I should sue the manufacturer for damages.
