Hi Fellas, long time reader of the forums only just registered so go easy! I had my Logic Board replaced on my MBP, following this repair I have been unable to stream any movies from my iMac to my MBP using iTunes. I keep all of my music and movies on my iMac on external drives. Music sharing still works fine but movies do not. The weird thing is that ALL sharing functions still work on my G3 iMac and my wifes old Dell laptop. I just tried to stream music using an sthernet connection to my MBP and it works a treat - so the issue must lie with the airport card in the MBP? Any suggestions would be welcome! Cheers Guys!
