After further troubleshooting, this appears to be the codec it is requiring:
www.libertyrecording.com/download/SpeexACM_1.0.1.1.zip
I have tried installing the codec along with the player & capturing it that way, but it still isn't picking it up. When I attempt to just capture the codec installation, the only entry point I get is cmd.exe. Can I use this and app link it?
