Rebooting did not help. One last question: the only change I have made to system is to set up a second email address to open emails thru iCloud on the ipad. Settings/Home Sharing on ipad shows apple id used by Apple TV. Could this change cause my problem?
If you are saying that you have added a secondary Apple ID through settings > mail, contacts, calendars on the iPad or system preferences > Internet accounts on the Mac for the purpose of having another email account, this shouldn't affect homesharing in anyway.
It doesn't actually matter whether you use the Apple ID you use for iTunes (or iCloud for that matter) for home sharing or not, the only requirement is it's a real Apple ID and you use the same one for home sharing on the Apple TV as you do on the computer.
