I Have Piles lets us know that on the Ahead website we can find an update for
the Nero Burning
ROM 5.5 software. Some time ago Ahead released an update for
the Nero 6 software which fixed several important bugs (such as the problems
with the Plextor PX-708A recorder). There is no changelog available for
this Nero 5.5 update but it probably fixes the same problems. You
can download the Nero v22.214.171.124 update here.
