I might be completely wrong but I don't think NetFlix works like that. It's a streaming app and their secret sauce for delivering content is always a live CBR connection with very limited hardware buffering. This means the content is never really on your device (except in small blocks that are meant for buffering and once sent to the screen, the buffer is cleared and ready for more). It's not downloaded and stored but rather sent constantly from the service infrastructure. So, in short... Not, you can't do that.
