I have checked the radio tuner connection here in CT several times...
1. Seems to be much faster and it apparently works....
2. After each successful access of a genre, a 'stram count' is displayed....the stream counts disappear when you quit and restart iTunes
3. Access of your shared library by a remote device (iPhone remote tested) accesses ALL genres and updates the stream display for all genres...
4. Personal observation: I think Apple couldfind a way to acknowledge the existence of significant issues...The comments in this thread were [except for the Angry Bird component...and problems like this can bring out the Angry Bird in all of us...] thoughtful and helpful. Many participants seem to be shareholders and long-time Apple customers. Also 10,000 people accessed this thread and there are several other threads on the same topic. I will probably still follow up on this issue even though this particular problem appears to have been solved.
5. Simon: my wife and I may visit NC and we can trade beers. You are the one who noticed first, I think, the scope of the problem since EVERY remote triggered the issue. I will contact you outside this forum re other audio issues.
6. Malcom: I will contact you via e-mail...appreciate all your positive input....
7. Annie: thanks for concise, positive, helpful comments....
Best!
