Hi Peter, I have the trial version of Videobuilder and it works ok with that - with the strap line added. However PTE gives the option of using Moviefactory. I already have this installed so I wanted to use it rather than pay for the registration for Videobuilder. But Moviefactory 5 Plus does not list ptev as one of the files it will import so I am puzzled by this. Has it been dropped from the 5 Plus version? Regarding AVI output, I have tried creating a custom AVI with full frame format. The file renders out but when I run the avi I find that the video is corrupted. I've tried creating a custom AVI in other Microsoft formats but just get a blank video screen in the rendered avi (apart from Microsoft video 1 which workes but looks horrible). I wonder if anybody else has been successful in creating custom avi files from pte. [i'm using WIndows XP and Windows Media Player 9 - no difference when I load up Media Player 11] I have tried older version of pte, eg 4.48 and the outcome is just the same.
