After a month of waiting finally this little Xtreamer turned up. So far everything I've thrown at it has played fine. Even 1080p.mkv!
I put a 500GB 2.5" HDD in and it streams from the NAS boxes as well (under UPnP)
They are making available their own NAS boxes in Novemebr and for existing customers they will cost about 60 Euro's each!!
grab a bargin if you are not using HTPC's
