Homesharing no longer available after latest iTunes and ATV upgrades.

Also, the little airplay icon in iTunes has vanished (the one right next to the what's playing now screen and allows you to send video/audio to your other devices.)

In ATV, the Computer icon tells me that I have to turn homesharing on to see media. It's on. I've done all that.

As recommended on the 20 or so other threads related to these nightmarish upgrades, I've also..

Disabled IMGP (whatever it's called)

Opened ports.

Configured bonjour.

Rebooted and even reset router.

Turned off windows firewall.

Restored both my ATVs to factory settings and downloaded and installed latest upgrades

Reinstalled latest version of iTunes.

Turned the computer off 46 times.

Made sure I'm on same network.

And other things I've probably forgotten over the last 3 days.

Odds of me having to revert back to older iTunes?

Oh and let me save you some time..
