I have a Dell Dimension 4550 with a DVD-ROM reader. I would like to change this to a DVD-RAM reader as I have a Panasonic DMRE55 and would like to copy from RAM discs to my PC so that I can burn to DVD-/+R. I have an External DVD writer which does not read RAM. Could I do this myself, is it easy, and what DVD-RAM reader can anyone suggest? Can I, for example, buy an external DVD-RAM reader? By the way, I am extremely pleased with the Panasonic DMRE55. Excellent results and so easy to use.
