Thanks for your feedback.
yes that was my thought on it to regarding software. but i noticed on github there is a fork or something that is called MOI
on the buildroot for tvheadend i found this
https://github.com/tvheadend/tvheadend-packaging/tree/master/buildroot
it might be possible to build it for that MOI unit myself.
if this box has closed software, or that i need to relay on TBS for software upgrades, its a no go.
but i hope it should be possible to isntall everything on that unit from scratch myself if that is the case i might try it. it cost only 499$
