While Boxee, the company, is no longer in existence, the Boxee software and Boxee Box still do work although it is somewhat limited. The online streaming that Boxee was originally designed to aggregate has lost a lot of capabilities over time as streamers either blocked Boxee from streaming the programs or Boxee technology just couldn't keep up.... flash update anyone? That being said, I still use my Boxee Box everyday to play files from local hard drive as the Boxee is still great at organizing TV shows or movies in an easy to use format.
While this website originally reviewed and rated the apps available for Boxee, many of those apps no longer work so I've stripped down the site to some tips that I find valuable for finding videos to download as well as a few repositories that still provide some useful streaming capabilities.
And if you're feeling adventerous, you can even hack your Boxee Box for additional functionality...or even install XBMC on your Boxee Box. Visit boxeed.in for more information about hacking your Boxee and a useful forum for discussing Boxee.
