ASF unable to write wma lossless file

Encoder Windows Media Audio 9.1 Lossless
Encoder Settings VBR Quality 100, 44 kHz, 2 channel 16 bit 1-pass VBR
Audio Quality Perfect (Lossless)
Type Media Center file    [.wma]

Able to read the file fine, but "Example #3: How to write ASF information" 
fails with:

PHP Fatal error:  Uncaught exception 'Zend_Media_Asf_Exception' with message 
'Operation not supported' in

Looking at IndexParameters.php:123 reveals that the exception is by design. 
What to do?
