Hi. I am capturing some video from a VCR to a Dazzle RCA -> USB adapter. When capturing from Pinnacle, the sound and video works perfect. However, after about an hour or so, Pinnacle stops capturing audio. It's like the audio has been muted. This has occurred on several times and I think it might be a problem with the software. Is there something I'm missing? Has this happened to anybody else? Thanks for your help!
