I'm currently trying to create an interactive PDF with embedded YouTube videos. However, whenever I attempt to embed any HTML object, I get the above error message. What does it mean? I also tried to embed a video from metacafe to see if it was an issue with YouTube and had the same error message.
I googled said error message and got no results.
Additionally, when I try to add a video via URL to an empty frame, it does not accept a YouTube video as a valid extension.
