Version: (using KDE 4.3.3) Installed from: Ubuntu Packages I have started to copy several of my data cd's to my computer. I have mounted the cd's widget, copied the cd, unmounted it, mounted the next cd. But then unfortunately dolphin did not show the content of the cd. I tried it several times, even with other data cds, but the content of none of the cd's was shown. I then used K3b to do the same. Then the content of the CD was shown and I was able to copy the files. So there must be a difference in how Dolphin and K3b handle it.
Without further details it sounds like a Dolphin issue to me. The CD being reported and mounted kind of hint toward solid doing its job, but Dolphin not displaying the right *content* of the CD (where solid is not involved).
