I am slightly frustrated. After SEVERAL tries to copy 31 minutes of a VHS family home movie to convert to DVD, I get an error message OSStatus Error-49. I have wasted several hours trying. I have over 30 gigs of available space on my macbook pro. I have already converted several other shorter VHS segments to DVD on my macbook pro. I do not recall ever seeing a limit to the file size. What am I dong wrong?
