From Christian Kindahl:
InfraRecorder is a free CD/DVD burning solution for Microsoft Windows. It offers a wide range of powerful features; all through an easy to use application interface and Windows Explorer integration. It creates custom data, audio and mixed-mode projects and record them to physical discs as well as disc images, supports recording to dual-layer DVDs, record disc images (ISO and BIN/CUE), and import session data from multi-session discs and add more sessions to them.
What's new in this version:
Version 0.52 added support for reading discs to a network location, fixed DVD-Video file sorting bug, preventing fully compatible DVD-Video DVDs from being created and devices with drive letters A or B are now detected properly.
