Yes ... you can just turn that plugin off

set enabled=0 in installonlyn.conf and it will never delete a kernel.

You could also add this to the CentOS-Base.repo file in
/etc/yum.repos.d/ in the [Base] and [updates] sections:

exclude=kernel kernel-headers kernel-devel kernel-PAE* kernel-xen*

then you will have to manually upgrade your kernels ... if you wanted that.

I will test the DVD playback issues and see if I can duplicate them.

Thanks,
