Has anyone successfully set this NAS up with an Xbox 360 and had it work to stream music or video?  If so what format is it encoded in?  I have my DNS-343 setup as a Raid-5 w/ 4 x 1TB drives, EXT3 file system.  I have setup the drive through the configuration page and I can see the videos listed on the X-box, however when I try and play a video I get an error.  This also happens when I try and view a JPG image or try to listen to an MP3.  Someone who has set this up and been successful, I would appreciate any suggestions you have.
Thanks in advance.
