I use Easy CD/DA Converter. It's a multipurpose tool that will burn audio, video or ISO. files to disk.
Also you can use it to convert file formats which is very useful.
I've had it a while so I can't remember what it cost but it wasn't expensive and imo it's much better than Nero and certainly much faster.
You might also consider the freeware burners such as IMGBurn and InfraRecorder.
Check out the software thread, there is a sticky about both free and paid software for this purpose.
Hope this helps, John
