Thanks a lot!
I'm testing right now Satdreamgr-4.0-gst1-et9x00-20160816.zip on my ET9200.
The image does not recognise TBS5925 by default, I had to install USB and TBS packets. After a reboot I had a crash while configuring the newly found tuner, but on 2nd reboot all seemed set up to continue. Now I am testing on 5ºW. Normal transponders are OK (11591 V) but I can't get any signal on MIS transponders (12627 H, 12648 V). Is this a symptom that I need custom satellites XML file or another problem?
