Which vo method did you choose? From what you say, it sounds like you
chose x11. X11 video output is very compatible (it should work on
anything that can run X) but does not use the hardware scaling
capabilities of your video card. So, when you go to fullscreen or resize
the window, video is not scaled for you. You can use software scaling
(beware of higher CPU usage) with the -zoom option.
Alternatively, it would be better to get a different video output method
working. Xv is usually the best driver to use from within X. I'm not
familiar with Radeon cards (or RedHat) and can't help you specifically,
but you should probably post the _entire_ output of
$ mplayer -vo xv somevideofileyouhave
Before you do that, though, read here:
The Xv section is section 188.8.131.52.1, right near the top of the page.

You can see which video output drivers are compiled into your version of
mplayer by typing
$ mplayer -vo help
As far as demuxers and codecs are concerned, mplayer automatically
chooses the best for most situations, so for the most part you won't
need to concern yourself with this unless you're trying to do something
more advanced. I don't mean to imply that it's really difficult, but
rather that it isn't necessary most of the time.
Good luck, and mail back if you want more help or clarification. And
don't be afraid of the Docs, either. :)
