Netflix-backed Roku is selling new versions of its set-top box. Earlier this year, the company offered a software upgrade that gave its standard definition player the ability to play HD content, as part of its deal to stream video from Amazon VOD; now users can get HD quality from the start with two new Roku boxes. The pricing and specs are as follows:

Roku says it has new content partnerships to announce “in the coming weeks;” it added MLB.tv to the roster in August. It plans to launch a “Channel Store,” which will give users the ability to sort through content by category, and customize which channels get featured on the home screen when they first turn the Roku player on.
