Hi, I have a wireless network running via the "old" airport extreme. When streaming movies from my G4 powerbook to my G4 mac-mini(which is attached to my TV) the video (almost) always "stutters", you can't watch it. Assuming I don't upgrade my network, will the AppleTV do a better job and not "stutter", or is it my wireless network that's the issue? Maybe I need the new AE? Running Tiger and Comcast broadband(with a comcast supplied modem). And my internet connection speed appears to be fine. Thanks in advance.
