npr radio stream--new file type?? 'wax'

have been using knoppix in live cd mode [klik and real player] to stream national public radio. going great.

today some 'listen' buttons would not work. get a 'wax' file instead of 'smil' file.

example of file name when saved to desktop--npr3244.wax
its described as plain text document

example of file content when opened in kwrite
<asx version = "3.0">

</asx>

ideas about what this represents and how to solve?

thanks.
