I have tried other file types, from Sony camera's, my GoPro and I also tried the Crib Menu HD m2v, that didnt work either. Here's a shot of the timeline with the shot exported from Premiere as a H.264.
I can uninstall Encore but when i start Adobe Application Manager, Encore is not listed. It installs as part of whats called "Adobe Premiere Pro CS6 Family". I would have to reinstall Premiere to do it and as I mentioned I really dont want to do that but as a last resort somewhere down the line, I may have to.
