Yea, when I load that in chrome, it just hourglasses. Works fine in FF. Seems the Video under "We Are SC links" uses some skin over flash (red spinning EPSN load bar) that has issues with all but the latest version of flash. My Chrome is using 11.1.102.55 while my FF is using 11.1.102.56. How about you?
Still not sure how it would cause your router to crash, but maybe if it creates a resource load loop, it could fill up your RAM on your router and crash it. Try opening like 5 720p youtube videos at once and see if that can crash it. Also, how many internet sessions do you see total? Once you get near 90-100 you start having problems.
