Can WavPlayer play .msv and .dvf files created by Sony handheld recorders?

The WavPlayer can play Sony .msv and .dvf files but a free "Plug-in" is required.  The plug-in can be downloaded from Sony's web site or by clicking here.  You do not need the plug-in if you already have Sony MemoryStick Voice Editor software installed on your computer.

If you continue to have trouble playing .msv file after downloading the plug-in, try changing the "Files of Type" to "All Files."  You can do this by clicking File | Open in the WavPlayer window, and then changing the field in "Files of Type" to "All Files."
