I am not sure how much memory my MATSHITA UJDA720 DVD/CDRW has. I have done a google search, but it didn't come up with any links giving the info. The documentation that came with my computer does not have any details on this either. I am triing 2MB and it works, but if I have more I would rather use it all :-) Anyone know how to determine the memory of a cdrw device? Rusty
