HDMU

Latest image for AzboxHD is version 16733 from feb.2017. I notice that many of their other supported boxes have a few releases since then, so I hope they havent stopped developing for Azbox
Forum is the same url as for the images
OpenATV
http://images.mynonpublic.com/openatv/nightly/index.php?open=azboxhd
Currently at version 6.0. They continue to creaty nightly builds, so these images are VERY fresh and most likely untested. In the forum there are two main categories - Receivers with support and Receivers without support. Azbox belongs to the last category, and judging from some of the threads these images are not to stable on azbox.
