It does not fix the problem where Apple TV won't show up in iTunes devices. At least not on my mac.![]()
Have you tried rebooting? Any time I have a problem with AppleTV not showing up, a reboot cures it every time. Apparently, there's a problem with iTunes if you start/exit it too many times in MacOSX (memory leak or corruption?)
In any case, I'm leaving my software where it is until I hear all problems are solved. 2.0 works fine here anyway and HD movies are ready to start within 1 minute on a 5Mbit connection. I haven't upgraded iTunes or Quicktime either since I read a lot of people got far more new bugs than they solved. Apple needs to fix old bugs before putting in new features that create a whole new set of bugs, IMO. I'm basing a whole house wireless audio system off iTunes, so it needs to be stable. iTunes 7.6.1 running off Tiger 10.4.11 with AppleTV 2.0 works fine and is perfectly stable (so long as I don't exit and restart iTunes too many times at which point a reboot fixes it like I said above).
I think my past problems with AppleTV not working right were caused by the devices not registering properly across the Internet. That's the only thing the Apple Store really did (adjust the account some how) and then both have worked fine ever since.
