Hello!
Here is a project called Ace Stream. They use modified VLC as their player and refuse to provide source code for it. There is a .patch for VLC 1.1.12 on their forums which was uploaded more then a year ago, but they refuse to publish new changes for current Ace Player, which is based on 2.0.5.
When I was asking for the source, Ace Stream administrator called me their license violator and I got banned from Ace Stream system without any explanation.
And there is a mistake in their license agreement. It says that Ace Player HD is provided under the LGPLv2 license, but VLC is GPLv2 and can't be sub-licensed.
I wrote about that some time ago on videolan@videolan email, but never got a reply.
