Hi, I was looking for some help here. I have created some ringtones (Less than 30 seconds and all are using the .m4r extention). If I try to add them to itunes some of them are showed on my Music section and some of them are not recognized. I have also discard the files are damaged due to quicktime is able to play them. Does anyone have seen this before? Any suggestion would be appreciated.. thank you for your help.
