Try "resetting" the iPad...
Hold the On/Off Sleep/Wake button and the Home button down at the same time for at least ten seconds, until the Apple logo appears.

HT4352 I have followed all the instructions on home sharing and it used to work perfectly. With the new apple OS upgrade my apple TV now longer sees anything, even though I I applied all home sharing settings again. Anyone know how to fix this?

I am trying to get home sharing to work on the applie tv and its not working after a Mac OS update. It has not worked for about a month and use to work fine. Has anyone else experienced this problem. Is Apple working on a fix for the problem? Is there a work around?
Thanks,
Anthony

A frequent cause of consistent failure to enable AirPlay or HomeSharing at all, is the service being blocked on the network. Make sure your network isn't hidden, has a unique name, that MAC address authentication is disabled, security is set to use WPA 2 Personal and that there is only one router/device acting as a DHCP server and providing NAT services.
Make sure your router/computer allows access over the following ports

Refer to your router manual/manufacturer for any settings that are specific to that model.
Another frequent cause of consistent failure to enable AirPlay or HomeSharing at all, is security software, in many cases configuring it correctly, disabling it or even uninstalling it can help, but in some cases the security software can cause problems that simply reconfiguring, disabling or uninstalling cannot reverse.
If you are consistently unable to activate AirPlay, have tried all the steps in this article and have security software installed on your system, you might benefit from contacting its provider or participating in any online forums they run to discuss the matter with them.

When watching Youtube, there is a lag between sound and video. Does anyone know how to fix this. It only seems to happen on Youtube.

Youtube starts ok, but there is a sound/video lag which becomes greater as the video continues. This doesnt happen on other sites which use video.

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Go to Settings>Messages>Send and Receive and sign out of the ID and sign back in. Note this will delete all old Messages from the iPod.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.

Hello there philp_69,
If I understand correctly it sounds like your phone hasnt been recognized in iTunes on your PC since the last couple of updates. I would use the troubleshooting in the following article which will walk you through the steps one by one.
iPhone, iPad, or iPod touch not recognized in iTunes for Windows
Thank you for using Apple Support Communities.
All the very best,

Try updating your iTunes using an iTunesSetup.exe (or iTunes64Setup.exe) installer file downloaded from the Apple website:
http://www.apple.com/itunes/download/

When I try to download the latest version of iTunes on my iPod Classic I get the message that "iTunes has an invalid signature" and that "Content was blocked because it was not signed by a valid security certificate. Anyone know how to fix this?

When I try to download the latest version of iTunes from apple.com, I get the message "Content was blocked because it was not signed by a valid security certificate."When I open iTunes and try to download the latest version there, I get the message "iTunes has an invalid signature. The download has been removed." I have also gotten an Internet Script Error stating that an error has occured in Line 0, Char O and that "Access is denied to images.apple.com/global/scripts/lib/iepngfix.htc."

Are you downloading iTunes form an Apple website or somewhere else? If the answer is somewhere else, try downloading it from Apple. Click on iTunes in the black menu bar above and go from there.
Let us know what happens.

My itunes ends up being so out of date becuase I can never upgrade it.
I have a sports kit and want to make sure I am using the most uptodate version
I managed to delete the old version, just in case it was the fact it was about 10 versions out of date that was the problem but now I can't reinstall it at all......
Please help

Go to Microsoft website to fix install and Unistall problems. Click "Run now" from Fix it to remove all iTunes & related installer files:

Welcome to AD!
I have a regular post for the top 3 or 4 fixes for that 9808 error. Obviously you are going to skip #1, since you've already tried it. Let me know how you get on with the next 2.
The top 3 fixes to itunes error 9808 seem to be
1) Go to Start > Control Panel > Internet Options > Advanced, make sure that SSL 3.0 is checked and TLS 1.0 is checked. Also under Security make sure that the “Check for server certificate revocation (requires restart)” is unchecked. Then click ok and fire up iTunes.
2) The culprit was Norton. The users are set up as Admin and Standard. I have Parental Controls turned on in both Vista as well as Norton. Admin users had no problems connecting to iTunes. Standard users would get the error. I had to go to Norton’s Personal Firewall and add the program “iTunes Helper.exe” and set the option to “Allowed” (”iTunes.exe should already be in the Allowed category.) in order for the standard users to be able to connect.
3) close iTunes if you have it open right now. Then go to C:/Documents and Settings/username/Local Settings/Application Data/Apple Computer/iTunes. Delete or cut the preferences.xml file which contains your iTunes preferences. Then go to C:/Documents and Settings/username/Application Data/Apple Computer/iTunes and delete or move the preferences.xml file. For Mac users, there is only one file you must delete or move a to a new location and is located at User > Library > Preferences > com.apple.itunes.plist. Restart iTunes and it will recreate those two (or one) files with the default settings. Feel free to set your preferences back to what they were and then connect to the iTunes store and enjoy!
And #4, see if you can get into the iTS from a different windows admin account on the same PC.

Error getting license. License server communication problem E_AUTH_BAD_DEVICE_KEY_OR_PKCS12. Does anyone know how to fix this? I have contacted the company that I purchased the download from, and they say it is an Adobe Digital Editions problem.

My phone app freezes and message app crashes. I tried restarting multiple times and the problem persists. Everytime i go to the phone app and press on a contact to call it just freezes up and does nothing. Does anyone know how to fix this problem?

My phone app freezes and when i press on contact either it freezes or does nothing. Anyone know how to fix this problem? Also messaging app crashes. ANOTHER NEW PROBLEM: I can't receive calls either.

Try to reset the phone by holding the sleep and home button for about 10sec, until the Apple logo comes back again. You will not lose any data by resetting, but it can cure some glitches.
If this does not help, setting it up as new device would be the next step:

My iphone dosen't doesn't make key tone sounds anymore when I write a text message or when I want to dial a phone number I don't know how to fix this problem, I don't hear the clicking noise anymore does anyone know how to fix this problem?

My iphone dosen't doesn't make key tone sounds anymore when I write a text message or when I want to dial a phone number I don't know how to fix this problem, I don't hear the clicking noise anymore does anyone know how to fix this problem?And all the sounds on my phone are on, even the keyboard clicks.

Try restarting your iPhone by holding down the on/off and the home buttons at the same time until you see the Apple logo, double check the volume button just in case. If you still can't hear the tones go into your settings>sounds and make sure the options are on.

I delete an individual message but the time I received the message is still showing next to the persons name in my inbox instead of going back into the correct date/time order. Anyone know how to fix this?

SOLUTION
Open "terminal" on your mac and type the following:
defaults write com.apple.mail IgnoreSortOrderWhenSelectingAfterDelete 1
(copy and past the whole line)
This will stop that behaviour in mail.
It works on most opperating systems.
mine is.
Mac OSx 10.7.2 Lion

You have to delete the corrupt back-up so iTunes can at least back-up the current data on the iPhone and then restore it. Search these forums, there a several good posts on how to delete the corrupt back-up.
