Burning a data disc from files in folder

I would like to know how I can make my Mac application (in Objective-C) burn a disc with any burner. I need to get the app to prompt the user to insert a blank disc, and once the user has inserted one, the program will start burning all the files in a specific folder to the disc, using the DiscRecor开发者_如何学编程ding and DiscRecordingUI frameworks.

There used to be an old demo for doing this with the 10.5 developer examples. I found a link to some sample on the apple reference library here that has a sample application for dvd burning. Hope that can help! I really wish apple still included the many examples that used to come with the developer package.
