Yes I have rpmfusion repos but the driver has been installed from official NVIDIA site. The suggested tweaks to reencode every file sounds very annoying. Coming to the royalties thing, I have to admit I didn't know that. What is confusing me is: - with the nouveau drivers the problem did not exist. - vlc and smplayer are not playing even AVI files. I'm seriously considering to revert back to nouveau. Anyway thanks very much again for your help.
