Windows DVD Maker

Hi, I'm new to the site, and am going to be building myself a new PC over the next month or so (first time builder, but I've enlisted a more experienced friend as well).

I'll be running Vista (I know it's not entirely perfect at the moment, but I don't want to go XP and have to go through the hassle of changing in a year or so), and I was wondering how powerful the DVD Maker software is. Does it have capabilities to 'mount' ISO files, for example? Or is it purely a video DVD editor. I've been googling this, but I can't find any info. If it is purely good for DVD videos, could you recommend some software that would give me a bit more functionality? I currently use an old version of Nero, but I don't know if it's compatible with Vista.

Cheers for all replies.
