MPlayer documentation: VIDIX
"There is a console VIDIX driver: -vo cvidix. This requires a working and initialized framebuffer for most cards..."
You can see here that MPlayer can't access the framebuffer.
Are you trying to play the video in a console, rather than in X?
Thanks for your quick response....
I am trying to play the video in console..
When I am using suse linux i usually play the video in console...but in RHEL i cannot do this.....
This is not a Codec issue. vo_cvidix is not a codec, it's an output driver.
It needs the framebuffer to display the video in a console. You need to have a frame buffer running. Usually the fb is compiled into the kernel and you just need to add an argument to your bootloader config, Lilo or Grub.
You can read more about Framebuffers at Wikipedia: Linux framebuffer

I'm not familiar with RHEL so things might be a little different...
but you should be able to find out if FB is enabled by looking at the /boot/config file
Look for lines like this. (y = built-in, m = module, n = not supported by current kernel)
Code:
CONFIG_FB=y
CONFIG_FB_VESA=y
(There might be more)
I'm not sure which bootloader RHEL uses, but you have to edit the kernel line, adding something like this
Code:
kernel /boot/vmlinuz root=/dev/hda1 vga=791
Maybe someone with more RH experience can provide the specifics.

my /boot/config-2.6.9-34.EL file looks like this.
