After installing (and uninstalling Roxio,) I have a problem with iTunes that I cannot solve. iTunes does not recognize either of my 2 cd drives, and I get this message: "Registry settings used by iTunes drives for importing and burning cd's and dvd's are missing . . . result of other cd burning software." I have uninstalled iTunes, Bonjour,and Quicktime, as well doing a repair to iTunes through add/remove programs. Nothing works. and I cannot burn, copy, import, etc. I have reinstalled iTunes 3 times so far. The Apple/itunes sites have been of no use. Any help will be appreciated.
