I'm trying to decide between the base Roamio and the plus model. Is anyone successfully using a 6 tuner Roamio with Time Warner Cable of SW Ohio? I don't really have the extra $200 but the plus model has stream built in, plus a bigger HD, and the extra tuners. I will beg, borrow and steel if I have to but I want to make sure I can actually use a six tuner model. thanks.
