I have a Moxi DVR which installed a fully licensed version of Play-On, on my PC. An added benefit though is Play-On feeds Hulu, Netflix, Amazon On Demand, CBS, ESPN, via the media server option to the WD TV Live as well. I do NOT have a Netflix or an Amazon account, but the other services (Hulu, ESPN, CBS), worked.
NetFlix is the holy grail for media recpetion devices, so I wonder how long the wait is before a deal is struck and a new firmware is available giving you access to Netflix, but if you cannot wait and money is burning a hole in your pocket, then Play-On might be a fit for you. There’s a 14 day trial so you can try before you buy.
