Expectations & Misconceptions
You will see people in this forum with different expectations than what the product advertises. It does not record video streams… it downloads them and places them inside an MP4 container (video file). You will never see a quality choice greater than 1080 between the Providers. However, currently D+ and Hulu only offer up to 720 content. If you are looking for a 4K solution, this is not the product for you due to HDCP copy protection protocols.
I can't validate this, but it has been reported that HMax can sometimes allow 4k downloads through AS.
