[CentOS] Centos issues

Hi i just swicthed from opensuse and having some issues that were not
present in suse.

1. add/remove software (package management)does not work. Opensuse
flawless working.

2. how to add dvd as repository. in suse it was automatic.


i choose centos b/c it has the longest upgrade cycle.

i am using centos 5.1 on vmware server


but if i cant solve it i will switch back to suse.


Thanks
