Reply to Help with some FLAC files

So I've been trying to make most out of my sets with lossless files and some of my buddies have suggested FLAC. I understand that they're great in terms of quality, but my CDJs won't handle them. Either that or I'm doing it wrong. I tried to burn them on an audio disk, but it's not working the way I thought it would.

How should I convert these without loosing any of the quality?
