Unfortunately I had no choice but move back to V9 receiver for the time being thanks to GTMedia Combo receiver is so buggy. Android operating system gets freak out and sometimes crashed.
However, will use for any 4:2:2 feeds comes from any breaking new feeds find here this fine forums or from Rick's website forums.
May have to find a way to make a and b switches between 2 receivers.
We use this 4-way splitter which has power pass on only one leg. This way you could make the V9 your "master" receiver and have up to 3 "slave" receivers
