first generation apple tv connect to iTunes 10.6
I have a wonderful first generation Apple TV (running ATV OS 3.0.2 which is final update for that product). It's a great product and still is in excellent condition. It is connected to the my home wifi network properly.
I have an older HD TV (rear projection) that is huge and has an awesome picture -- but it has no HDMI inputs; so all of the newer Apple TVs won't connect to it.
Apple keeps updating iTunes and omitting support for 1st generation Apple TVs.
So since iTunes 11 doesn't support it, I acquired an older iMac, running OS 10.5.8 and iTunes 10.6.3 (25) and I'd like to set that up as a dedicated machine doing nothing but supporting and syncing to my 1st gen Apple TV. This would include music files, music playlists, iPhoto galleries, movies & TV shows.
When I go to add the Apple TV, devices doesn't show up anywhere. All the trouble shooting pages I've read so far on the net say to check the box "Look for Apple TVs". That box doesn't exist and it seems many other people had that same problem.
I can easily get my Apple TV to produce the 5 digit numeric code which I'm to enter into iTunes but I'm vexed as to how to get iTunes to see it and give me a way to enter it, thus connecting the devices.
File sharing is turned on and firewalls are turned off on the iMac.
Please help.
