Just an update for the Austin guys. I was able to tune in CNN, HGTV, National Geographic just fine, so I'm not sure where the SDV info is coming from. I'm guessing these channels are not SDV today, but that doesn't mean they won't be tomorrow. ahaley42, I initially could not receive any of the channels in the HD package on one of my tuners. When I called TWC, the CSR said the system hadn't been updated to show that I had paid for the HD package service yet, so she said she "marked it as paid" and the channels instantly showed up on my end. I wish I had a better technical explanation of what she did. Not sure if that helps you with your premium channels, but in my case, it was more of an administrative problem than a technical problem with the cable card.
