Sounds like there is a way to do the multisession DVD.
Could you elaborate a bit?
What about the issues that Dodecahedron and Pranav brought up?
If multisession is not reliable, is DVD useful for doing backup of files that are modified regularly, or is it better for archiving lots of files that won't need changing?
At present I format CD-R discs so I can drag and drop files from Windows Explorer, perhaps I should continue with this method for files that are updated frequently. What say Ye?
