Using Closed Captions with Captivate Quizes

I’ve been adding closed captions to a captivate project.  However, the quiz slides will not show the “closed caption” text.  The “CC” button is on the play bar.  I’m also using quiz questions from “random question pools.” Have I missed a setting? Thanks

Flash videos

I’ve been given a captivate file that has an embedded Flash video.  I want to copy and convert the flash video to an MP4 file and reinsert it into the captivate project.  Then publish as an HTML5 file. Can anyone advise me on the best way to accomplish this?  I’ve also been given the file in a zip format with the scorm files. Thanks so much.
