2 Houses - Question - TWC TV and Apps

I have a home in South Carolina and one in New York. I have Time Warner Tv in the south - a "full package" - HBO, Cinemax, Showtime, etc. Currently in NY I have Directv. If I switch to a Time Warner basic package in NY - can I use the ROKU to access my channels in South Carolina? I spend half the year in the south and half in NY. Will hthey come through in full HD mode?

This question is about "2 Houses - Question", with Time Warner Cable TV and apps.
