install vlc on acer aspire one linpus linux

hello friends

i have tried follwoing the instructions

efore you proceed to install VLC you may want remove the pre-installed media players.

sudo yum remove pdvdlinux mplayer\*
sed /pcmmvp/d -i $HOME/.config/xfce4/desktop/group-app.xml

To install VLC just add both repositories and use yum.

sudo rpm -Uvh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm
sudo rpm -Uvh http://rpms.kwizart.net/kwizart-release-8.rpm

sudo yum install --enablerepo=kwizart-testing vlc mozilla-vlc

If you used the instructions posted here to install Firefox 3 an additional step is required.

sudo ln -fs /usr/lib/mozilla/plugins/libvlcplugin.so /opt/firefox/plugins

The commands below put an icon on the desktop.

sudo sed s/%U// -i /usr/share/applications/livna-vlc.desktop
dca add 12 "file='/usr/share/applications/livna-vlc.desktop'"

A reboot may be required for the changes to become effective.

However when I do the first rpm command i get depedency errors as below

Retrieving http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm
warning: /var/tmp/rpm-xfer.VVDQdt: Header V3 DSA signature: NOKEY, key ID 49c8885a
error: Failed dependencies:

I have no idea where to go from here and have failed to find any similar posts so any help is appreciated.

Thanks
