Query: Extensive but buggy

Version 6.0 is extremely buggy - there are fixes for many of the problems on the Roxio website, but quite a few aren't fixed. I was unable to burn a DVD with this software, but at least the software prevented me from even trying to burn the DVD, so I didn't waste the DVD. That being said, if you can get it to work, it's very extensive. You can also burn audio CD's from .wav and .mp3 files, with CD-text, and then import the track information to the label-maker. Pinnacle's Instant CD+DVD might be more suitable for you. They have a trial version so you can make sure it works on your computer before you buy. If all you're looking for is DVD-authoring/burning software, try Ulead MovieMaker 2; they also have a trial version.
