UPDATE: There was a significant bug in the firmware regarding Netflix Canada, but it has since been fixed, and I'm updating my review and rating.
This is a great little media player that will handle most any video format you throw at it. I avoided the potential issues of configuring Windows 7 to share folders, by using TVersity media server, which works great with this box. I just turned off all transcoding, as this little gem plays nearly everything without it. The menus are clean intuitive, and the interface is customizable.
You might be looking at the cheaper, new Canadian Roku box, but take note, the Roku does NOT support DLNA streaming from your PC. Dollar for dollar, you can't beat the Western Digital.
