Mplayer mozilla plugin install problem with yum

[Chap]

I was trying to set-up linux on my friends PS3 and get this error when trying to install the mplayer plugin
with yum. This error occurs when yumex is checking GPG signatures.

/nerror checking package signatures:
yum.errors.yumbaseerror

I installed yumex on his PS3 with the same yum.conf file that I am using. I also installed mplayer through this
sites instructions and it works as well. I have the mplayer plugin working on my machine but can't figure out why
this error keeps coming up on his. There was even an update in my yumex for the mplayer plugin that installed no problem
on my machine. Any help would be appreciated.

Thx.

If things are set up, just go to add/remove software, then do a search for mplayerplug-in .

I was able to get it working by starting over from scratch. Yumex worked perfectly this time with no errors.
