// using a memory stream, I recived a System.ArgumentException
// the painful peice being that I could't pin point which argument
// was invalid. For those of you at home, you need to setup the
// waveFormatTag FIRST, then create the buffer. This peice I
// missed when reading the instructions as it is done automatically
// when loading from a file but if your copying a memory stream
// it obviously doesn't know what exactly is in the stream, so
// you need to define it - even if you are copying an existing stream..
// If any one from Micr0$0ft reads this - I would really think a few
// more examples would be handy when your dealing with parts of the
// api which aren't going to return freindly error messages..
