Hello there, since i was unable to find a universal binary build of this reference encoder for mac, i did a build myself.
Another user on this forum fixed the libaudio.a dependencies, etc, so what i did was to fix some compiler defines to make it work under both PPC and Intel based mac's.
I also migrated all the sources to an xcode project so it's easier to build and mantain for anybody.

Here is the universal binary build: DOWNLOAD

Here are the full sources moved to an xCode project: DOWNLOAD

Oh good, does anyone know how this compares in quality to running the nero encoder in wine?

I think that the nero one is better, but i needed a native solution for mac, that was the reason because i built this one.

Maybe the guys at nero.com should think about building a Mac binary ? ** hint **.
It should not be really hard to port the linux one that you already have
