I've a Pioneer 108 as the present DVD writer/reader in my G5. I read in the specs at http://www.cdrinfo.com/Sections/Reviews/Specific.aspx? ArticleId=10114 that I should be able to read DVD-RAM at 2x speed. How do I do that? A DVD-RAM disk is in a housing, and it seems that this housing will not fit in the present mechanism. Paul Moortgat
