Recovering lost sessions on a dvd

I recently burned a multisession dvd using nero 6.The problem is that when I burned the second session the first session dissappeared although its physically there on the dvd. I know how to recover the lost session using a software called “Iso buster”.

My question is it possible to recover the first session on the dvd and burn it back to the dvd so i can access it from windows explorer without having to use Iso buster.I want the lost session to be reburnt back on the dvd so I can access it like a normal “undeleted,active” session.

additional info: when I burned my dvd using nero 6 I selected “make data disk” (from nero start smart).”Allow files to be added later” (multi session disc) was checked and “Verify data on the disk” was unchecked in the burning settings.
