xine error:"warning: user machbuild does not exist - using root"

[ashwin kesavan iyengar]

Hi,
     I was trying to install xine by downloading xine-0.99.2-1.1.fc2.fr.i386.rpm
from freshrpm.net then it reported ( when i did rpm -ivh
xine-0.99.2-1.1.fc2.fr.i386.rpm)
warning: xine-0.99.2-1.1.fc2.fr.i386.rpm: V3 DSA signature: NOKEY, key
ID e42d547b
error: Failed dependencies:
	libaa.so.1 is needed by xine-0.99.2-1.1.fc2.fr
	libxine.so.1 is needed by xine-0.99.2-1.1.fc2.fr
	xine-lib >= 1.0.0 is needed by xine-0.99.2-1.1.fc2.fr
I thought it probably needs xine-lib-1.0.0-0.14.rc6a.1.fc2.fr.src.rpm.
Downloaded that that & tried to install when it reported the error.
The error message was :
warning: xine-lib-1.0.0-0.14.rc6a.1.fc2.fr.src.rpm: V3 DSA signature:
NOKEY, key ID e42d547b
warning: user machbuild does not exist - using root
warning: group machbuild does not exist - using root
(something like ################################# here)
warning: user machbuild does not exist - using root

how do i install xine in my machine or is there a player build-in to
play back DVD movies?

thank you,

with regards,
