I have a small problem with a Vu Zero running Openvix 5.3.034 where I can see blocking/artefacts on playback of some video files (e.g. .mp4 files). I've tested different HDMI cables, and different TVs but the problem remains. The same files play perfectly on 2 other older Vu Zeros running 4.2.026 and a Vu Solo4K running 5.2.034.


I think the problem may in part be related that this Vu Zero is a Rev 2 box - it came with the newer style remote, whereas the other two Vu Zeros came with the older style remote (red LED flashes on button press).

I thought initially if I flashed the older version of OpenVix it might help, but I can't seem to flash the Vu Zero with older images (5.3.019 is Ok, but 5.3.002 failed) - described here:

Could anyone advise?
