I am unaware of any DVR on the market that has ever or is Energy Star compliant. As for having DVR off or out of standby, no unattended recordings. My hunch is that DVR's are adifferent beast wit a need or better, more reliable perfomance and longevity with a fairly constant load, especially constant updating so that the device and conumer expectation of INSTANT on, recording, access experience. For many devices, the whole lower power and Energy Star qualifications are more about marketing and making some people feel good. An HDD, or any electronic device with constant, stable load will outlast the wear of frequnt surges to power or spin up. There is a cost, albeit a different cost, but a higer out of pocket cost when it comes time to replace the expensive electronic device for being penny wise and pound foolish. Now, let's never use the central air, wash by hand, hang to dry, use an ice box, never vacume, get rid of our A/V surround sound, throw out the power hog PC's (monitor alone before factoring in the CPU, etc.), cease use of hot water (always on to heat water heaters waste, but tankless water heaters require copious draws of electricity to fas heat the water), and more and we can really make adifference on power use so profound that powerplants could be shut down. While we are obessed with the drip of water, there are rivers of water being wasted jus a few inches away.
