Not sure if you received help already but try this link, it worked for me....
Download the DRM Packager 1.35 for your operating system.
Unzip and Install.
Open Sony "Ericson DRM Packager"
Select file to "convert" (i'm assuming it's an mp3 file)
Click "Create DRM Content"
It will create a folder called "DRM" - open it.
It would have created a file of type:- "Forward-locked or Combined delivery content file"
Send this file to your phone....
Hope this helps
for those who have mp3 issues, flash the phone to z800i FW to fully play mp3's

i like this phone but voice in the headspeaker its very bad so change the speaker please other wise stop making this
i am very enthusiastic about this phone,but i have a problem.i cannot use the melodies as rigtones because it says they are not key-protected or something like this.if i want to use a melodie as ringtone the option is not highlighted,thehefore i can't do it.Please help me if u can.Thanks
i think the drm is the protection files of the music. Like the asf and asx. it has a drm protection. whats the main difference of having an upgraded v800 to z800 than the original z800?! my brother told me that even if you upgraded the firmware still you cant use the mp3 as a riinging tone. he had 3 of this v800 upgraded firmware to z800. about the signal, he just fixed it by buying an antenna wire and replacing it. hope it helps!
