Maybe Apple TV will allow bit perfect streaming so

I'm certainly not an expert about this but all the discussion I've read about dealing with jitter, regardless of whether it's an Airport Express, Squeezebox, CD transport or other device, has focused on using an external DAC that reclocks the signal or a purpose-specific device inserted between the output device and the DAC to do the reclocking.

BINGO!

Does anyone know how to fix the AE jitter problem. Better PS / Caps? Junk it out and start over?

Just substitute 'airport express' for 'appletv' in the URL Aberyclark provided, http://www.apple.com/feedback/airportexpress.html

Does a similar feedback site exist for Airport Express?

I'd like to know what I could do to fix the jitter problem.
