I've been using mplayer to view videos till today, when I decided to try out totem and gnome-mplayer. Both totem and gnome-mplayer play videos smoothly and with good sound, but the colors are different from the ones I get with mplayer. Totem and gnome-mplayer both display the same, but I think the colors in mplayer are correct. Skin tones in totem look bluish. Totem and gnome-mplayer seem to be displaying red where mplayer displays blue and vice versa.
Are there any sample videos that I can use to find out what's going on? The videos I've been looking at are in AVI and Windows Media formats. The system is x86_64 running F10 with an Nvidia GeForce 9500 GT with the proprietary Nvidia driver. The colors displayed by all other applications look quite reasonable.
Any help would be very welcome.

If red and blue appear to be exchanged, you can try to correct the error by using the "hue" control of the players.
Either you have accidentally changed the hue in your players and the settings have been saved, or (quite probably) there is a bug in the players or graphical drivers.
Also try to see if there is any difference between mplayer with -vo x11 and with -vo xv.
Testing vlc would be another data point.
Best regards.

As you suggest running mplayer with -vo x11 displays normal colors, and -vo xv displays "reversed" colors. Is it possible to control the video output method for totem and/or gnome-mplayer? If so, how?
I suspect there *is* a bug in the driver, since I've never seen this problem before. Maybe it's time to switch back to the free drivers. I'd like to report the bug, and (as I wrote before) a test file would be extremely useful for this.
Vlc is available from the rpmfusion repo. What are its special good qualities as compared with mplayer and/or totem?

I'm not an expert with GNOME apps, but if you run
gstreamer-properties
and go to Video/Default Output/Plugin, you can switch xv acceleration on and off and see what happens (there is a test button playing colorbars). (apparently you can also run it two times, side by side, to compare)
But I'm not sure if totem and gnome-mplayer obey that setting.

It could be a bug in the driver. You really don't need a test file, you can just say that "colors are wrong when applications use xv acceleration". But, it may be that the problem is not in the driver, just in the decoding library the players are using (ffmpeg?).

This is why I suggested a test with vlc. If you can get good colors from vlc in xv mode (called xvideo in the vlc pref panel), the driver is ok.
Vlc is just another good player; I personally still prefer the no-GUI mplayer.
Best regards.
