How can I use the CDA files on my audio cd as background music for my show?
The CDA files shown on an audio CD are not sound files. They just contain the information where to find the music on a CD. To use music from an audio CD you have to use an audio grabbing program which copies the sounds to the hard disk and converts them to wave, mp3, wma or another sound format. There are a lot of programs you can use to do this. For example the Windows Media Player.
