I was posting in this and that thread about my problems and they called me back saying that the TA's they have (don't have model atm as I'm at work) only support 2 streams (hardware/software limitation). And basically don't hold my breath on them upgrading the hardware anytime soon. So, that means it can only support two SDV channels at once (this would explain what I was mentioning in the threads above). So, that leaves me with some *not great* choices. Try to buy my on TA that supports 6 streams and see if they will support it. Try disabling 4 of my tuners so my SDV channels will come in properly all the time. Wait for Brighthouse to upgrade their hardware and live with what I have atm.
