Hello first time poster, but long time reviewer! Well the time has come that I have completely swapped over to the Apple platform after being with Windows for over 20 years! Its a slow transition, but after my whole house rebuild of Apple products totaling around 8k I better get full use out of it. OK, so here is my question. Do I need the Airport Xpress so I can mirror with my MBP, or Ipads to the Apple TV? More detail on my question below .. So I have purchased the Airport Extreme 3TB Time Capsule. From what I have gathered both on the web the Airport express is used for Airplay. I guess what Im confused about is this .I know that the Airport Express has the digital/optical out for audio. Correct me if Im wrong but wouldnt that just be beneficial if you wanted to say connect some speakers to it so you can push your iTunes stream? In other words you (Dont need it?) if you want to push your itunes music, videos, pictures..etc wireless, to your ATV use the Airport Extreme? Finally, I just wanted to clarify if I need to purchase it. All my routers get great signal thought my house so no need for an express as an extender. So I really couldnt use it their, but if it IS needed to stream from my ipad, MBP, and iMac to the Apple TV or to use mirroring then I guess I will need to buy it. By the way, my Apple TV will be hooked up to my TV using HDMI cable. Then my TV has an optical out that runs to my stereo. Basically whatever HDMI video I have selected on my TV it will drive the audio to my surround sound speakers. Thanks in advanced!
