I have the same problem with Sony SoundForge and I am trying to find out a solution for this issue at Sony SoundForge Forum too. Until the present time, we have no solution for that case.I remember that I had some problems with Windows Media Center – BSplayer, VLC and Winamp Player and I had to uninstall all of them and re install just VLC and JetAudio and fixed Windows Media Player too. Maybe the issue comes from that codecs mess! I don`t know. I have used lots of registry cleaning software but could not solve that issue. If you guys find some way to solve this problem, please let me know.
Best of luck!
