YouTube’s HTML5 embed player works great and flawless but why not switch to the old flash player to remind yourself of the good old times when flash ruled 😜.

Youtube Flash Player Embed Code (Obsolete)
Like you did in above step, simple replace the embed url with the flash version url. Here is the syntax.
<iframe width="500px" height="294px" src="https://www.youtube.com/v/VIDEO_ID"><iframe>
OR
<iframe width="500px" height="294px" src="https://www.youtube.com/embed/VIDEO_ID?&nohtml5=1"><iframe>For quick and easy embed I would recommend using youtube embed code generator where you can customize a ton of options like changing youtube embed thumbnail,player technology,etc.
