That channel has been on Directv for a long time now, but can't be seen in venezuela because they refused to show their president speeches and breached some laws that indicated they HAVE to broadcast the speeches (if more than 70% of programming is local), they can be seen in a lot of countries but not in venezuela, maybe what they'll do is they will also be on the Amazonas satellite (Telefónica Digital) at 61ºW, owned by Hispasat, as a pay tv.
From my understanding, RCTV was one of the 3 most important channels, and the 2nd most important who is against Cháves, the other being Globovisión, nowadays available at SatMex 5.
