Totem Problem

[mus1402]

i have installed Fedora Core 4.Im newbie to Fedora. I tried to use Totem. It stated this error:
"Totem could not startup
Resource busy or not available"

So my questions are:

1) What should i do to resolve this problem?

2) Can Totem(that come along with fedora) play DVD and VCD (im not talking about totem-xine) ?

Thank you very much

You need to install multimedia decoder to play audio and video files.
