I have lots of footage using HD camera with 5.1 surround sound in AC-3 format. I used to edit this with no problems, until I got a new PC with Window 11 and reinstalled MEP 2015. When I try to load this footage to the timeline it says I need a free update (I think it might be related to Dolby sound), but this will not download or install. If I ignore message, footage plays fine and the mixer shows the correct surround channels (5.1). However, when trying to author the project for Blu-ray, I get the same message about needing this download, which I ignore, and then the encoding is aborted with Error No. 5. If I switch format to Stereo sound, everything is fine.

I think I need to upgrade my video edit software, as I really want to be able to edit this footage retaining the surround sound. Will Video deluxe plus or premium enable me to edit these AC-3, 5.1 channel files and output surround in another format (AAC?)? I want to burn Blu-ray disks for some of the movies too. I believe this is all the result of Dolby licensing being withdrawn?

Thanks for your advice
