It is not possible to download content from streaming services like Netflix or Hulu. These services are designed to stream content to you over the internet and do not provide a way to download the content to your device.
Some streaming services may allow you to download certain content to your device for offline viewing, but this is typically only available for a limited selection of titles and is not a general feature of the service.
If you want to watch streaming content when you are not connected to the internet, your best option is to use a device that has the ability to store and play back content, such as a portable media player or a laptop with a DVD drive.
