Thank you for your reply!
Sorry, but I'm sure that's not the problem. I'm already using an image format that supports the alpha channel.
The Alpha channel actually is there, but it doesn't really act like a MATTE shader would do...
I'll try to explain better with a picture... I'll post it right away.
