hi all, I'm still having trouble getting hbo (and encore channels) to work on the s3. when I try tuning those channels, I get the cablecard message that it considers the host to have one way rf only. I've had 2 comcast visits, just because comcast insists on visiting, and the situation hasn't changed. both times they tried new cablecards, and left saying they'll forward the issue to their supervisor. I haven't heard back from comcast. has anyone had a similar situation, and had it fixed? btw, I'm able to get the current showtime promotion just fine. seems like something in the signal?
