Converting Nero TO DiscJuggler?

[vsp]

A couple of reasons behind my madness:

1) I have full (purchased) versions of DiscJuggler and CDRWIN. I haven't bought Nero yet. If I can convert Nero NRGs to CDI images, I may not need to buy Nero as well.

2) On my system (Athlon 1300, 256MB, Win98SE, LG CED-8120B), I can burn at 12x using DJ 4.0 with no problems. Burning at 12x in Nero produces buffer underruns, and burning at 12x (sometimes at 8x as well) in CDRWIN also produces coasters. I haven't had any problems with DJ 4.
