I've recently lost one channel on both of my Premieres with the dreaded "Problem with the signal on this cable channel. Trying again." I've had Charter out three times, but they mostly just tune to the affected channel, verify that the ones above and below work, then kick to the next level of support. We tried swapping out one of the M-cards this morning but that didn't help. While on the phone with TiVo this afternoon, we noticed that the firmware version string on these (Motorola) cards looks odd: "02.65, -.-, 03.25" Does anyone know if there should be something in that middle field, or what the current FW from charter (Georgia) ought to be?
