I have just bought one of these boxes, it is running the latest firmware (not the damaging .12), and is connected to my full hd Philips LCD TV with a good quality HDMI Cable.
The problem is that I get occasional pixelation when I playback MKV files on the box, this occours wheter the HDMI out is set to 720P or 1080P. I have tested that the files does not contain high reference frame count and they don’t(max. 5 ref frames in 1080 files).
This happens on both 720p and 1080i MKV files.
The pixelation occours randomly, and if I rewind the file after it has occoured, the same passage can playback without pixelation.
I have tried playing back files from different sources, USB Stick, USB Hard disc, and the result is the same.
The files of course playback flawlessly on my PC.
Seems like some sort of buffer issue or a faulty unit.
