I have installed CentOS 5 with mplayer -1.0-0.34. from de dag's
repos,everythings going well while I'm just listening music ando doing
any easy job, but when I run yum the mplayer stops for a while and start
again, the sames happens with xmms.
I have a celeron 2.9ghz and 256mb ram  
I want to know why is this happening ?
