Western Digital has released a new set-top box that will let you stream and play high-definition multimedia from your home network or local drive to your television screen.  Without any extra effort in encoding or decoding, you can play your DVD or Blu-ray ISO files as well as AVI, MKV, MP4, MP3, JPEG, and many other file formats.  The Western Digital TV Live Plus will surely change the way you watch television!Wait a minute…haven’t we heard of all this already?  Well, sure, Western Digital did release the WDTV Live in late 2009, so this new player must be a tremendous upgraded in hardware technology, right?  Well, actually, the WDTV Live PLUS has the same Sigma 865x chipset used in the ‘old’ Live, and Western Digital says it plays the same types of media files and codecs that the older version does.  The new Live PLUS retails for $119.99 which is only a bit higher than what it costs you to get its $104.99 older brother. The retail box has been updated slightly to highlight the WDTV Live Plus's ability to stream online content.
