Q: atv not recognizing the 5.3 update, but is obviously connected. Help

Hello Chucanuka,

I suggest a couple of things. First restart your Apple TV in this manner from Apple TV (2nd and 3rd generation): How to restart your Apple TV, found here http://support.apple.com/kb/ht3180.

Restarting your Apple TV (2nd or 3rd generation) using the onscreen menu

If you have Apple TV software 5.0 or later installed, you can restart your Apple TV using the onscreen menu. To restart your Apple TV choose Settings > General > Restart.

If after that you still cannot see the update on the Apple TV, then I recommend restoring it using iTunes.
