@Ingo: Please find attached a test build using an updated mediasink for azbox. It was build against GST 1.8.0 from oatv, but I copied over to HDMU image on my ME and it appears to be working (as in not crashing). (you should copy all 4 files from the attached azboxdvbmediasink_for_testing.zip )
Could you test how this works for you. As you have a working mediasink (the old one linked in other thread), can you make some screenshots (owrking/not working). My ME may work , where your Premium doesn't.
