Hello, I'll like to know why I can't hear any audio when capturing video from a VCR? The image is captured and recorded fine but I can hear the audio only after I recorded a video segment and playing back the material recorded. I'm using a Steren 445 COM adaptor to capture the VCR signal and Dscaler software Alpha 4.2.2 My PC is a HP mini with Windows 7, Intel Atom. Thanks in advance for your help!
