Having a problem playing DVF files using Windows Media Player. I have downloaded the Sony plugin 1.23 and still I can not open and play DVF files using the Windows Media Player. I have also tried to use Express Scribe but each time I attempt to load the file it tells me I need to load the Sony plug in for Windows Media Player. Which of course I already have (several times!). Appreci ate any assitance available. I am using Windows 2000 Professional OS.
