How can I stop my buddypress activity page from freezing?!!

Hey Everyone, I am using your latest version of the BuddyPress Activity Plus plugin. Now my BuddyPress activity stream is freezing (freezing for like 15 seconds) whenever I scroll through it when there are videos in the stream and it freezes if I leave the page and then go back to it. This is only happening on the main activity page and the profile activity page.

How can I fix this? Would changing the video iframe size help?
