How exactly are you inserting the video? For example, are you just dropping the Camtasia MP4 into a RoboHelp topic? Or did you output from Camtasia using the Smart Player and you have added all the different Camtasia output files to RoboHelp and you are linking to the HTML file Camtasia supplies?
The video is saved to my computer (desktop) and I am using the Insert/Multimedia/Demo function within RoboHelp. The video needs to play within the RoboHelp output. One topic has written information and the user also will play the video within that topic. I hope that makes sense.
