Thanks for your replies. What you say above sounds plausible because I have libdvdread-4.1.3-1.el5 installed, but gstreamer-plugins-ugly-0.10.11-1.el5.rf.i386.rpm is looking for libdvdread.so.3.

Per your recommendation, I searched the centos wiki but got thousands of hits, read through the first (and most relevant) hits and found nothing which seemed relevant. So I browsed around, found http://wiki.centos.org/PackageManagement/Yum; it didn't say anything relevant.

Then I found and read http://wiki.centos.org/AdditionalResources/Repositories?action=show&redi.... This page does mention specific repositories, but I don't see where my yum repository setup doesn't conform with what the wiki describes:

# pwd;ll /etc/yum.repos.d total 88 -rw-r--r-- 1 root root 302 Dec 21 11:48 atrpms.repo -rw-r--r-- 1 root root 2882 Oct 23 14:20 CentOS-Base.repo -rw-r--r-- 1 root root 2323 Oct 5 00:51 CentOS-Base.repo.v.3.4 -rw-r--r-- 1 root root 267 Jan 13 12:06 centos-livecd.repo -rw-r--r-- 1 root root 600 Oct 5 00:52 CentOS-Media.repo -rw-r--r-- 1 root root 954 Apr 25 2008 epel.repo -rw-r--r-- 1 root root 1054 Apr 25 2008 epel-testing.repo -rw-r--r-- 1 root root 1070 Dec 6 2008 livna.repo -rw-r--r-- 1 root root 739 Jan 4 08:55 mirrors-rpmforge -rw-r--r-- 1 root root 436 Jan 4 08:55 rpmforge.repo -rw-r--r-- 1 root root 325 Jan 4 08:55 rpmforge-testing.repo

Are all those repos enabled? If yes, you for sure will run into problems. This list has a history of examples.

Moreover, after erasing my installed libdvdread, I did: # yum install libdvdread .... ================================================================================ Package Arch Version Repository Size ================================================================================ Installing: libdvdread i386 4.1.3-1.el5 epel 54 k

Transaction Summary

Install 1 Package(s) Update 0 Package(s) Remove 0 Package(s) ....

Isn't epel pretty much a standard repository?

"Standard" in which way?

You already found the right wiki page

http://wiki.centos.org/AdditionalResources/Repositories

which explicitly says:

"It may not mix well with other 3rd party repos. So, make SURE you are using the Priorities yum plugin if you are using EPEL ... especially if you mix its packages with those from other 3rd party repos."

If I'm missing something of what you're saying, please clarify and/or be more specific, because I'm not seeing where in yum the problem might be.

Be selective with the repositories you use. Make use of priorities and protectbase yum plugins. Using ATrpms, EPEL, livna and rpmforge alltogether, you will see lots of conflicts.

rpm -qa --qf '%{NAME}\t\t\t\t %{VENDOR}\n' | sort -k4

can help you to see from which source you already installed which package.

Thanks again, ken
