Squid Cache/Squid Guard and mobile Videos

[Streat]

I currently have squid and squid guard running for advertisement filtering and its simple cacheing features in a home environment. You tube works wonderfully with advertisements blocked on computers but all flash videos show a play button with a slash through them (not allowing them to be played) from ipads and iphones and rokus. If i disable squid as a transparent proxy i can play the videos but i lose all of my advertisement filtering.

I am sure i am missing something extremely basic, does anyone have any suggestions on how to work around this?
