How do I get rid of "other" storage

How do I get rid of "other" storage or why is there so much dedicated to it?

PLEASE HELP!

I have an iPod touch 32Gb 4th generation with:

- 19Gb of music

- 2Gb of TV Shows

- 3Gb of Apps

- 3.3Gb of "Other"

Here is the troubleshooting attempted:

- Not syncing music or TV Shows.  Result: I still have 2.1Gb of "Other

- Not syncing apps. Results: No difference

- Restoring iPod with lastest backup: No difference

- Restoring iPod from scratch and putting back everything back on: No difference.

I am out of ideas.

Please, please help!

Thanks.
