This mplayer configuration file can play 1080p perfectly and smooth

it was tested on Athlon X2 4000, and Sempron CPU, and only 1GB Ram (Gentoo Linux)

make sure you have your Video drivers configured and set
Such as nvidia, ati(fglrx) and intel.
I think it should also work on any P4 or Athlon XP

put this on ~/.mplayer/config
(create it if it's not there)

~/.mplayer/config

# Write your default config options here!

#======
# Video
#======

vo=xv
# Use double-buffering. (Recommended for xv with SUB/OSD usage)
double=yes

# Use 16MB of ram to cache the file
# Increase to 64mb if you have spare Ram.
cache=16380

fs=yes
ni=yes

# Video Output postprocessing quality 
# This sets the postprocessing into overdrive using all possible spare cpu cycles to make the movie look better
# if  you have older CPU such as Athlon XP or Celeron, comment this.
# Fast Machine: 90
# Slow Machine: 10
autoq=50

# use this for widescreen monitor! non-square pixels
# My monitor = 1440x900 == 16/10
# Change this to your monitor.
monitoraspect=16:10

# Subtitles

# Align subs. (-1: as they want to align themselves)
spualign=-1

# Anti-alias subs. (4: best and slowest)
spuaa=4
# try 3 if your cpu is not so fast.
# From mplayer man page:
#                 0    none (fastest, very ugly)
#                 1    approximate (broken?)
#                 2    full (slow)
#                 3    bilinear (default, fast and not too bad)
#                 4    uses swscaler gaussian blur (looks very good)


# Set language.
slang=en,eng

#===================
# Text-based subtitles
#===================

# Find subtitle files. (1: load all subs containing movie name)
sub-fuzziness=1

# Set font encoding.
subfont-encoding=unicode

# Set subtitle file encoding.
unicode=yes
utf8=yes

# Resample the font alphamap. (1: narrow black outline)
ffactor=1

# Set subtitle position. (100: as low as possible)
subpos=100

# Set subtitle alignment at its position. (2: bottom)
subalign=2

# Set font size. (2: proportional to movie width)
subfont-autoscale=2

# Set font blur radius. (default: 2)
subfont-blur=2.0

# Set font outline thickness. (default: 2)
subfont-outline=2.0

# Set autoscale coefficient. (default: 5)
subfont-text-scale=4.4

# OSD

# Set autoscale coefficient. (default: 6)
subfont-osd-scale=4.4

Without this config the 1080p video plays terrible

NOTE:
1080p = 1920x1080 pixels
