It appears HD Netflix Watch Instantly streams aren't just for living room set-top boxes anymore now that Netflix is streaming more than half of its 720p-encoded titles to Macs and PCs (through the Silverlight web player, no word on the Media Center add-on .) According to, you can tell which ones are ready to go by checking the mouseover box for the (HD Available) tag as seen above. Our experience matches several other reports that not everyone is seeing the tag on all the same titles, so until it's rolled out fully, YMMV. It's not the new release flicks or surround sound add-ons that many are waiting for, but it could slide PQ up another notch for HTPC owners and everyone who just has to watchat work -- but you'd never do that.[Thanks, @DaveZatz
