I have installed MPlayer from dag repo on my CentOS 4.1 and codecs from MPlayer site. When I try to watch some movie file I get an error:
[... cut ...]
Open mplayer, go to the preferences, select video, and select something different under available drivers. Xv usually works for me, but your system could be different. One of them will work for you. The rest of that stuff you posted is cruft. It's looking for a remote control, a joystick etc. that's not a big deal.
OK. I have checked all video codecs the way you said above - still the same. Every change video codec I have restarted MPlayer.
