Nero Linux 4 problem burning multiple CDs



I am having a problem burning multiple audio CDs from an nrg file using NeroLinux 4. Nero will crash the system by the the 3rd or 4th burn. I have tried three different machines and two different nrg files. I always get the same result whether using Debian 5, Debian Testing or Linux Mint 9.
I had used this program happily for several months with no problems, but now that I must produce a quantity of a single CD from a stored nrg file, I find great instability and about a one third coaster rate.
The same nrg file is easily burned into multiple CDs on a Windows XP machine with Nero 6.
Any ideas would be appreciated.
