apple tv only shows computers and settings

Hi,

Since I updated my Apple TV to the latest OS, it only shows the settings and computers icons. This problem seems VERY common and the only advice Apple seems to have been able to offer does not work.

I've tried home sharing on and off, signing in and out, turning on and off, resetting the unit etc. Nothing seems to work.

Anyone got any suggestions other than 'reset your apple tv'?
