I disagree.

Regarding user-friendliness they are about the same to me. Can you point out something that I maybe missed that makes mplayer "definitely far more user-friendly than vlc"? (not rude, just curious)

edit: missed a word

While it does require some terminal skills, as far as playing or streaming any media file and skipping left and right a bit (the largest part of my contact with a media player) or shuffling through a music library goes, I find it far easier to work with.

I feel that people too often confuse a user-friendly interface with an intuitive or noob-friendly one. But I guess seeing as most programs' user base's large majority are non-technical people that's fair.
