The CDBurner application is geared for burning audio CDs — just drag an audio file in any format known to the Media Kit (MP3, WAV, AIFF, etc.) into the burn window and go. Because CDBurner uses the Media Kit for this, it’s also capable of detecting the audio track in movie files. For example, try dragging a bunch of AVI movies into the burn window. The resulting audio CD will contain just the soundtracks from those movies (other movie formats should work as well).
If you want the actual movies, you’ll need to burn a data CD rather than an audio CD. Read Creating Data CDs at BeNews for more information.
