Nero crashing on large nvc file



Nero Vision Express3 ver has been crashing on me when the nvc file has the details of over 20 clips in it.
The crash occurs if I try to Edit Movie or Create Chapters.
This is on Windows XP Professional SP 2 with P4 3.2 Ghz and 1024 MB RAM.
The size of the NVC file is now 10 kb.
Any ideas on how I can burn a DVD with a large number of small clips. All the clips came from my own camera.
