Hi there. I just started uploading old home movies onto my iMac. Some seemed to have issues with "snapping" or popping while it was trying to upload. I am using Roxio"Easy Vhs to DVD capture" and half my tapes seem to upload perfectly and the others are popping.... so that the pic is perfect, then jump with a popping sound.. and it does this through the entire tape. I am using one of those VHSc to VHS converters through a connected VCR. I am hoping this is not an issue with the actual tapes. They did not do this a couple years ago when I started this project (but had to stop because my mac crashed)...

Any help would be appreciated. Thank you!
