is now available, according to developer
Radical Breeze. This major update to their CD- and DVD-burning utility allows you to: burn audio CDs from the Audio tab; burn audio CDs from QuickTime-compatible files with audio tracks, such as MP3, MOV, AIF, WAV, and MP4; burn a CD with an audio and a data session; and save a pre-existing volume or folder as a DMG file, in addition to ISO. In addition, it features several interface tweaks and speed improvements.
You can use DiscBlaze to burn data to both CDs and DVDs, burn audio CDs, burn multiple sessions to the same CD, save and load Burn Lists, burn an existing Toast or ISO disc image file, and erase rewritable media. In addition, if you have Mac OS X v.10.3 (Panther), you can create a new ISO and DMG disc image file and make an ISO or DMG image of an existing folder or volume.
You can download and purchase DiscBlaze 3 from the Radical Breeze site for US$19, with discounts for larger volume purchases available. The new version is a free upgrade for registered users.
