try this MacPrince, I found it on another site:
To remove ringtones from the ringtones tab in iTunes, first delete the ringtones from the "ringtones" folder in the finder, then rebuild your iTunes database according to http://docs.info.apple.com/article.html?artnum=93313
Thanks, I needed that too. And yes the ringtones sync again w/ .m4a extension, but you now have to place them in the folder instead of just double clicking them.
TV that adds support for subtitling (and alternate audio tracks?), I think we can start waiting for the next Apple announcement on expanding the video offering to other countries. Of course there are contracts that need to be signed for each country, but at least the technical side would be then in place to support this expansion.
