cmh38- I hate to be the one to tell you this but in your search engine you can type, "wma to mp3", and get an entire list of converters. I picked the one at the top of the list. Here you go. www.smartaudioconverter.com I am not trying to be mean but common since answers a lot of questions. Good luck.
are you just trying to rip the audio out and have it as wav or mp3, or is there something else you would like to do
Try http://www.afterdawn.com/software/audio_software/audio_tools/arial_audio_converter.cfm It is a WMA, WAV, MP3, etc... convertor. If you have already burned a DVD-R you can not change it, because it is a one time burn only, but if it is a DVD-RW, you can save it in the new format and reburn. Or if you are going to make a new DVD-R you can convert before you make it and save it as MP3. You're not using a Solo 9500 with an external DVDRW drive are you?
