Tvheadend

Hi Everybody,
I sold my PCTV 460e because I did not get it up and bought the following Reciever:
https://www.amazon.de/gp/product/B01M00X69Z

I would like to use this Reciver on my QNAP NAS (
QNAP TS-451 +). The QPKG of "virtualdj" from the QNAP.com forum unfortunately does not recognize this Reciever, which is why I set up a Virtual Machine. This is Ubuntu 16.04.

Here is the Reciever immediately recognized in TV Heading. I then prepared everything and set up a mux (Astra 19.2). I live in Germany.
Unfortunately, after about 5 minutes I get the status: "PENDING - FAIL".
The log says:

Loglevel debug: enabled

Can any of you possibly help me? I just do not know how to go on.
Drivers are available from the manufacturer here: [[http://www.dvbsky.eu/Support_linux.html]]
thank you in advance

Maurice
