Maybe they use the same code, but it appears dolby digital sound, provided by the Surcode plugin, is limited to 3 trial uses. I ran into this myself last night. It would be nice to have it included in Premiere, but plug-ins cost money, even in bulk. I’ll be going the extra step with Encore if I need the extra space that Dolby will save me over PCM, or if I have to get more sophisticated than Premiere allows me to easily do.
Good luck
