iTunes Alternative?

[tkbx]

I've looked around, and so far, I cna't find an itunes alternative for Linux that suits my needs. I need:
m4a support
mp3 support
m4v H.264 "Apple Universal" video support.
Movies and TV shows, as seperate categories for iPod sync
iOS 5/iPod touch 4g support for syncing all of the above.

Does this exist?

Banshee seems like a viable alternative to iTunes, based on the criteria you've given. It uses Gstreamer as its backend, so it ought to be able to use all of those formats.
