sudo apt-cdrom - d /media/cdrom-1 add

[Joan perez]

Hello community: 

I have a small problem after installing ubuntu  dapper from a cdrom
"ubuntu desktop 6,06 LTS", I have downloaded  3 dvdrom and 1 cdrom with
bittorrent with the repository: 

- main-restricted (dvdrom)
- universo-multiverso-1 (dvdrom) 
- universo-multiverso-2 (dvdrom) 
- universo-multiverso-3 (cdrom) 

In order to adding  local repository with order "sudo apt-cdrom add" did
not mount dvd because I have a   reader of dvds  and a  recorder of
cdroms. 

I had to install the local repository from dvdrom with the order: 
sudo apt-cdrom - d /media/cdrom-1 add 

I installed the local repository from  cdrom with the order: 
sudo apt-cdrom - d /media/cdrom0 add 

PROBLEM:
Now I cannot use the local repository that I have added because SYNAPTIC
continuous mounting indiscriminately from cdrom (/media/cdrom0), if I
prove to install programs with "sudo apt-get install" the system mounts
in exlusiva cdrom and if I attempt from the SYNAPTIC menu to add cdrom
(from dvd) of repository happens the same, single never mounts cdrom and
when I introduce dvdrom it gives a assembly error and I can single
finish the installation cancelling. 

Somebody knows that it is possible to be done? 
 
Thanks.
