I recently moved from Houston, TX (had Comcast and they were great) to Austin, TX. Got my cable cards (SA PKM800's) and tuning adapters (STA-1520's). Generally everything works okay, but when changing channels, some channels display blank. When going into the Tuning Adapter menu and going to DVR diagnostics, tuning to some SDV channels display that they are analog channels, like HBO 1672. I'm not sure what is messed up, if it is the cable card or tuning adapter. It seems that perhaps the channel map is messed up somehow. A pull of the cable card and reinsert makes it work for a while (and a reboot yields the same results) but then it begins to mess up again. I have rerun guided setup, swapped cards and TA's with TWC, and it still yields the same results, on both my Roamio and Premiere 4 any suggestions / guidance anyone has would be greatly appreciated!
