Its a little more complex than that, since I'm using Retrospect to 
write multiple sessions on DVD-RWs for backup. But that's the general 
idea - the way the disks handle multiple sessions is different. In 
practice, I'm not sure there's any difference between the formats in 
terms of the way software can use them to provide multi-session 
features to the end-user.
