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.
