Hmmm... DirecTV carries Root for me here in NEPA.... and the cable co around here carries it also. You are just a couple hours due north from here... up I81.... but you may have a very different situation there. Because it is still PA here, and the Steelers are very popular up here, and the Pens have their minor league club here, they carry Pittsburgh stuff without having to go to a premium package.
I checked DirecTV for you and to get Root Pittsburgh... you have to go to the PREMIUM package and that gets EXPENSIVE ($100/month). You should however be able to get CBSSN on one of the less expensive packages ($45/month).
Otherwise... I checked ESPN3 and also the ACCDN and neither of them are carrying the Dukes game (CBS has the rights). I cannot check for the first RSN game as it is too far out there.
Here is the link to the ACCN. They sometimes carry games but it might just be games otherwise on the ACCN... but I don't know.
