Remove Enclosure thing.

Halla.
I’m using audio player plugin. WordPress creates a enclosure for the .mp3 file that I’m hosting on my domain.
The MAIN problem is that everyone who is subscribed to my feed will receive in mail, at the end, something like: ” This posting includes an audio/video/photo media file: Download Now ” . Under Download Now it’s my link and that’s not good at all ! I don’t want to experience legallity issues with artists/labels.
So all I want is to remove that line from Feeds… thing that might be possible if the enclosure is removed.

I found a similar problem here on WordPress.org right here:

Now I can see that code above.. where should I post it.. what should I do in order to have it workin’ ?

I’m waiting for an answer asap.
Thanks in advance.
