[SOLVED] Problem reading CD/DVD's

I inserted a CD and copied the files from it to one of my HD’s and then removed the CD, then inserted another CD.
I let it be read then clicked on the name of the CD on the left of Dolphin but nothing came up and I know there are filed on the CD.
How do I make it read it properly. I had this sort of problem before but can’t remember how I fixed it, is it something to do with the drive cache or something?

I’ve noticed the title of the CD stays the same as the first CD I inserted.

Think I’ve fixed it…
In the Dolphin Drive listing on the left, I saw ‘Release *********’ and clicked that and it worked.
