No, libxine is GPL v2+.

I don't know what this means. Are you saying that if I add a media
codec exemption it makes no difference for now but might in the

Codeine has been around for a while and I think has proven itself as a
good video playing solution.
I do share your concern about parts of trunk/KDE becoming a wasteland
of mostly unmaintained software. This is kind of what happened to
kdemultimedia in KDE3. We should be more aggressive in pruning
software in trunk/KDE. This shouldn't scare us into a situation of
just keeping everything in extragear, even software being released on
the KDE schedule. Kind of just shuffles the issue around.

Plenty of distros release to the US, only Novell and Redhat seem to
very concerned about media patents.
The only way (currently) to make a phonon video player that meets
Novell and Redhat's criteria would be for someone to buy a Qt license
and develop a video app with it. I'm happy to be told otherwise, I
could be very wrong since neither am I a lawyer or Novell and Redhat.
