I think that my problem in the end was a third party application that I had installed to allow me to use mod files. Once I had copied the ac3 dll from after effects and put it into PP everything went a lot better – it rendered the video on import and was able to edit it a lot better…

Do you have any 3rd party pluggins installed for this reason?

Otherwise everybody will tell you its the initial video format… and they all know a lot more than me, i just managed to ‘wing’ it to be honest…

good luck!
