why does the connection drop every other second when streaming from iplayer through safari to apple tv?

I am trying to listen to iplayer radio through apple TV from my macbook air. When I switch back to just using the macbook the stream is consistent and works well but when I switch to airplay mode the sound stream literally drops in and out every other second. Ha! I have just gone into iTunes and I have the same issue!?

I have checked for software updates on both apple devices and restarted my router but still I have the same issue.

This is really annoying as this is the main reason I got apple TV! Can anyone help??
