My Apple-TV can't connect to the iTune library on my MAC
I have turned on home sharing in iTunes on my computer, made sure my software is updated, and set up Apple TV with the same apple ID as for the itunes on my computer. I could access my iTunes library via apple TV for the first few days, but now apple TV can't seem to connnect to my computer (iTune) anymore. I have checked all the regular trouble shooting suggestions, but still not working.
I can still access the iTune store on my computer, and on my apple TV, using the same apple ID, but my apple tv can't access my itune library on my computer, in the same home network! Please help!
Apple TV, Mac OS X (10.6.8), Apple TV can't access iTune library
