Force Nero (6) to use more Memory?

With Sony Vegas Movie Studio one can set the amount of memory for the app to utilize (got mine using 1.5Gb) for rendering.

Is there a similar feature in Nero (or it’s registry settings) to up the memory being used? Currently, it’s using little more than 256Mb.

I have 2Gb to work with (& 512Mb PF).

Thanks!

ps. Nice club you got here. Been sitting on the fence for a couple of months. Glad to join!
