Thank you for The feedback. To be precise I have a multiswitch SCR provided by SKY Italia. It works fine with the MySKY decoder and works fine with the VU+Uno4K with Open BlackHole 1.0 and BlackHole 3.0.4. It stops to work with the last release of Open BlackHole 4.1 and BH 3.0.5. If I downgrade to the previous version it works.
