im not familiar with that software as my experience capturing tape is recording it straight into final cut or premere. my suggestion is when you press start record. just walk away and dont touch anything on your system until its done. i know even with final cut if i alt+tab or apple key tab
that it will stop recording and slap me with an error message. my understanding as to why is limited other than whenever i hit record i dont touch anything until im ready to press stop. if that doesnt help then my only suggestion is to either try different software if its available or return the cord and try a different brand if thats an option.
im going to email a friend of mine that has captured tape in the past and see if he has any experience with the same cord you have or anything similar as well as software. if i had his number i would call, not sure why i dont have it
but as soon as i here back you will hear back from me
im determined to figure this out because ive never heard of this issue happening to anyone
