/*
* Huge todo: this code works fine on Windows 7, but doesn't work on Windows 2008 Server. The problem is two fold:
*
* a) The two mp3 encoders installed by Win7 (l3codeca.acm and l3codecp.acm) don't exist. I see no way to "install" them.
* This site comes closes to explaining, but these reg keys do NOT exist so the solution doesn't work:
* http://blog.komeil.com/2008/06/enabling-fraunhofer-mp3-codec-vista.html
*
* b) The alternate option explained here:
* http://stackoverflow.com/questions/5652388/naudio-error-nodriver-calling-acmformatsuggest/5659266#5659266
* Also doesn't work since the COM object for the DMO isn't registered on Win2K8. The Windows SDK is supposed to have it,
* but it doesn't install properly on the server. Also Win Media Player won't install with a weird "There is no update to Windows Media Player".
*
* I've googled for a long time, but this is a tricky one. Maybe Microsoft needs to be contacted?
*
* This is required to create WAV files for Firefox to play. Otherwise you have to click on a link. (alt solution: embed?)
*
* NAudio.Wave.Mp3FileReader reader = null;
* try
