I'm interested in buying a movie video from Amazon, under their "Amazon Video Compatible Devices" it says:
HD playback is not available on all devices. For example, some Roku and TiVo devices don't support HD content. The Kindle Fire HD is HD compatible, along with Windows computers that meet the content protection (HDCP) requirements.
Please check your device owner's manual for more information about HD compatibility.
So... I don't know how to check for this... can anyone help?
