How to convert wma into wmv

How do I convert a wma file into a wmv file?? I am working on a C# program and it will not recognize that a wma is an audio file. Any help would be great.

if you have vista, drag a song into the vista movie maker then save it as .wma

if not, go to folder options and allow extensions to be viewed

then right click and rename delete EVERYTHING and save as .wmv

i dont know if that will work, it might

thats because of the encoding, visual studio i think will only recognize .wav as an audio file without extensive code

Yeah, I figured it out. Thanks.

What I did was use a Windows Movie maker form and dragged it into C# form. It works well.
