error 95 (no mountable file systems)

[shroom360]

I have a macintosh osx, my computer can't mount cds/dvds anymore (after about a minute or so it will spit them back out) I also cannot mount dmg files. When I try I recieve the error message : error 95 no mountable file systems. I've tried using different programs to fix this ( dmg fixer, mount, disk copy) none have been successful. I've also repaired disk permissions. I'm not sure what else I can do to fix this problem and any insight on this would be greatly appreciated. ^^

Verify you have all the latest updates installed. As well as repairing permissions, repair the disk.
