Video playback is choppy

[HanDy_man]

My spec Sempron 1150 LE 2GHz, Radeon x1200 (series) integrated, 1GB DDR2 800MHz. So when I play video it's choppy, it's tearing, and image is very crisp (I've try Totem and VLC with different renders). Games runs fine. Can someone tell me how to fix this problem. xorg-driver-fglrx (1:7.1.0-8-3+2.6.24.13-19.45) My xorg:

# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by failsafeDexconf, using
# values from the debconf database and some overrides to use vesa mode.
#
# You should use dexconf or another such tool for creating a "real" xorg.conf
# For example:
# sudo dpkg-reconfigure -phigh xserver-xorg
