I just started using mplayer minutes ago. I am running RedHat 8.0 on a Sony VAIO PCG-F540. Out of the box, the player works perfectly. I installed the latest RPMs including the CODECs and went to play some quicktime clips taken with my digital camera and it works perfectly. No complaints about it functioning. My chief complaints are in the way it plays. The video window should not be open unless there is video playing or displayed (i.e. video loaded but not playing) The logo display, which I cannot find a way to remove, is too large and annoying. mplayer does not respect window size and placement on the screen. If I set a playlist of multiple clips, it resizes and moves the window over and over again with the beginning of each new clip. If I select double-size, it goes back to normal size with each new clip. I would also like to see simple options like "looping" and repeat play. I would think "repeat" features would be relatively simple to implement. I think if those things are implemented, then this player becomes everything the home/desktop user needs in a media player.
