Hi Olivier,

I have two questions about the copyright assignment policy

1. I have copied contents from 2 xine source files
http://www.koders.com/c/fid2A05C6548F86F9EEFAB16C6EF6957928FEB56387.aspx
http://www.koders.com/c/fid151BE377E1A54F9BCE32102C1C185D60DE623BFF.aspx
Will this be a problem? I guess not, it's all GPL, right?

2. Will I be credited as the plugin creator?
This is not mandatory, but I would like to be credited as the plugin
creator.

Rui
