Hi Hejira, thanks for your answer!
After a reinstall I checked what you wrote and found out that streaming of SD-Channels with the option "Stream Current Channel" works. But I still do not have the entry in the Bouquet menue.
I read in an other forum that maybe an old Enigma2 version in this pcd-image may cause this "problem". The missed entry to add Bouquets of the partner box supposedly is available in newer versions.
Please, could someone validate this?
Thanks
