I have another Sony HDTV mated to a Sony BluRay player with built in wireless. It's running Nextflix fine right now. Second reboot of Apple TV and second reentry of my Motorola password. All the Apple TV seems to be able to see is my iMac's iTunes.
powered down router, even though it was working fine with another TV running Sony BluRay with built in wireless, and powered down Apple TV. Now on my fourth try, and it still is stuck trying to set date and time. This *****.
I dismantled my Apple TV setup and moved it to where my iMac is plugged in directly to my ISP. It still hung up on date and time, with the router out of the setup. Apple Service Call scheduled for 9 am local. I will post results. Thanks.
