Very belatedly, just want to say enormous thanks to you Carsten for this info and the full explanation. Really appreciate your help in my hour of need.

By the way, is there a list anywhere of the websites to download certs from all the main manufacturers?

Hi Jim,

unfortunately, not all manufacturers are so open with this as Dolby is (now). The Dolby site works for Doremi and Dolby DSS servers.

Other manufacturers will react to individual inquiries.
