My mom is going over to japan for work. Her friend at her who works over there uses slingbox to watch american tv. I looked at the slingbox and realize im gonna have to hook the box to my directv dvr so it can stream the video over the net to her laptop over there. My question is how does she change the channels on the directv reciever because all i see for hookups are componet and rca hookups. Also for anyone who has one of these whats the picture quality like and do you have any problems with this?
