[CentOS] Update Issue

I come to you "hat in hand" again. For the first time in a long while
I got a "Update Notification" at the bottom of my screen -- so I
decided to click on it and run the update. Unfortunately I got a
couple dependency errors and am not sure how to solve them. (Not even
sure why I got them.)

They are as follows:

Missing Dependency: libavcodec.so.51 is needed by package
transcode-1.0.5-1.el5.rf.i386 (installed)
Missing Dependency: libx264.so.55 is needed by package
transcode-1.0.5-1.el5.rf.i386 (installed)

The only non-CentOS repositories I have enabled are Adobe and
RPMForge. (I have, however, downloaded files individually from PBone.)

This is the first time I have had any problems for a while. Have I
broken something?

(I did find libavcodec.so.51 at PBone, but it won't install because it
wants the libx264.so.55, which I haven't been able to find.)

Is transcode what I use to convert CDs to MP3 files? I did recently
add MP3 codecs to Juicer, so I could convert my CD collection.

And I did try to update via yum after running 'yum clean all' and I
got the same dependency issues.

Thanks for any pointers.
