Winavi video converter can convert avi to dvd . And it can support almost all video format to dvd/vcd... and burn them on discs. But it may be unable to convert wma files.
it can make a dvd mp3 disc (every program can do that) or it can make an audio dvd (it is in pcm format. it would be the equivalent to 7 audio cd's). this is something different than dvd audio
