Bought this unit two weeks ago and have been playing with it for some time.
Updated to latest firmware and got going.
Ripped Enter the Dragon from Blue-ray and the movie shutters. Frames are not playing in order.
Tried (for experiments & educational reasons only) several downloaded HD (720 and 1080p) movies form PB. MKV are hit and miss, sometimes they work sometimes we have the same problem as with WD TV live, problems with audio.
I took randomly 15 movies (720 & 1080p) and converted them to .mp4 using standard profile using Turbo .264 HD stick. Result - most movies unwatchable. They shutter along and you feel somehow the the HD can not keep up. Very disappointing.
