Hi baguawald
Sorry you have not had any response to your problem, I don’t use 3D video so have no idea how to create that template.
I guess others on the forum may be in a similar position, hopefully 3D users may respond.
Corel do have a facebook account, we have had feedback that they do infact reply, and its free unlike the 90 day support, not used it myself.
Sorry I cannot be more helpful, I did look at the 3D template options and Share Create Video File 3D, the DVD option did allow for DD 5.1 audio. To be honest I don’t know what MVC option is?
As I say try facebook
