I think I remember a post and threads on this a while back. We are receiving CSN HD with no problem here in Northern VA. I was temporarily disconnected while moving residences when the RSNs went to HD(around Labor Day I thnk) and only found out about the RSNs being in HD after reading about it in this forum. I had manually punched in channel 629(after being disconnected) and the Caps game wasn't in HD, I thought that was kind of strange since I had read via this site that the RSNs had went HD, was just playing with my remote and hit the channel selector expecting to go to channel 630( after being on Channel 629), to my surprise when the channel changed it I got "another" channel 629 and the broadcast was CSN HD, so I have 2 channel 629's one in HD and one SD. Am sure you have discovered this but just trying to help. Why technically is Baltimore gettting the RSN in SD and DC/Northern VA getting the signal in HD?
