There is probably no driver available for our old kernel setup. We don't really put any effort in DMM anymore, we don't have the time to reverse-engineer their closed source.
There is a community effort on the way to look at DMM support for OpenPLi 6, maybe they can be of some assistance. You may have to use Google to search the forums.
The sound like a new box i the right choice !!!
Is VU+ Ultimo 4K HD a god choice ??
It all depends what you want to use it for and what other hardware you are attaching it to.
4K all the way ends in a Sony 4K proj to 260" screen, want S2 end T2 in same box in Sweden all channels in HD is on T2. so is Vu a good box or is it a problem box
