As for recording on USB key: Live it works but I have never succeeded deferred if the adapter is off it turns on but does not see the key and if I leave it on at the end of one moment he can not see it either :(
Note: not supplied HDMI cable (like almost Always) and very short cord area!
Despite these small flaws is a good device for those who, like me, have a HD-READY TV with an SD tuner!
