Why on earth do you want to record streaming movies from Netflix?
Netflix streams live. There are too many issues with live streaming that cause interruptions in your bought and paid for rental and lessen your enjoyment. If you could download it first (which Netflix doesn't let you do) and then play it back you can avoid the bandwidth issues that stop Netflix in it's tracks and stops your movie while it waits.
If I record Netflix movies with
screen video capture software, I also get choppy videos, so there is no point for me to record anything from Netflix with screen recorders.
