Support for Netflix streaming video has finally made its way to Boxee’s set-top box, the company announced today in a blog post.

Netflix support was the most common user request for the Boxee Box, the company said, and for good reason. The feature wasn’t available when the Box started shipping in November — at the time Boxee said that it would be available by the end of 2010. Obviously, it missed that deadline, and it also missed another deadline it set for the end of January when support for Vudu video rentals was added.

With Netflix and Vudu support, the Boxee Box now has a bigger selection of streaming video content than when it launched — but it may be too little too late to make it a viable competitor against Roku’s streaming boxes, the Apple TV, or even Google TV. Boxee actually had Netflix support up and running during the Consumer Electronics Show early last month, but the company apparently had a tough time ironing out the bugs.

Even though Boxee first announced the Box — which is built by D-Link — in December of 2009, it didn’t make its way to users until almost a year later. Hardware issues, including a switch from Nvidia’s Tegra chip to Intel’s Atom, likely led to the delayed release.

To get access to the Netflix feature on the Boxee Box, you’ll either need to manually update via the Settings menu, or wait for the automatic update to land within the next 24 hours.
