I'm using the Media panel to add a video via URL. It gives the option of setting up "navigation points" which can then be the basis of a button action. But if I try to create a button to play from a navigation point I get an error with exporting with In5:
I responded via email, but the answer might help others, so I'm adding it here. The video placed from a URL produces an error in InDesign that says, "Download failed because the URL could not be verified." I pasted the URL in a browser window and got a message that "This site can't be reached." It's likely that is the source of the exporting error.
