I am looking at coming back to DirecTV after moving and trying out Charter. The HR34-700 looks like the way to go. I would need place the HR-34 in the den and I would need two more HD boxes for bedrooms. I have several questions. I will not have any TVs that will be able to RVU so I will need HD boxes. What HD boxes should I hope to get? Also I noticed the fan inside the unit like most DVRs have. How hot does the HR34 get? Just out of curiosity.
