I have a video tutorial located on my YouTube channel. Q: Is it possible to insert a YouTube video into a topic in my help file?

In my help file, I have a video in one of the topics, which automatically begins to play when selecting the topic in the left hand side of the .CHM file. Is it possible to turn off the "auto play" option, so the user of the help file can play the video manually if he/she needs so. Please advise.
