Nero 6.0.0.19 Plextor PX-708A - problem creating multisession DVD+RW disc

Setup:
Nero 6.0.0.19
Plextor PX-708A writer
Windows XP Pro

Problem: When creating the first session of a ISO multi session DVD+RW disc the burn is successful but after the leadout the DVD is not ejected and Nero hangs the computer so a hardware reset is required. The session appears to be burn fine however as another session can be added successfully and Nero behaves itself. The same “lockup” happens if you try to create a new layout with the “continue multisession” option but the DVD has already been closed.

These problems are not evident if you use the UDF format

Has anyone else experienced this annoying bug?
