jacksutherl This is the universal video player, which has been enabled on sites that opted into the auto setup with Ezoic. The universal video player supports instream video, which typically is seeing the highest CPMs of any ad locations on sites (often times 3-4x standard display ads).
If you would prefer to not have this running on your site, you're welcome to turn it off under Ad Types > Floating Video. If you would prefer it is lower down the page (which you mentioned), we can also adjust where the video player shows on your site. No sweat one way or another.
I have adjusted it further down the page for you just now, but let me know if you're still seeing issues.
