yum update failling

[GweeDo767]

I am new to Fedora and just installed Core 4. I am trying to do a "yum update" but getting the following error:
--> Running transaction check
--> Processing Dependency: libdc1394_control.so.13 for package: ffmpeg
--> Finished Dependency Resolution
Error: Missing Dependency: libdc1394_control.so.13 is needed by package ffmpeg

I have removed ffmpeg and mplayer (which installed ffmpeg), any idea's?

Thanks.
