I see that KNSD has added two additional sub channels. TELX-HD (39.20, 1080i) and TELX-DT (39.21, 480i). They both seem to be broadcasting the same programming, which in itself is a waste of bandwidth. The bad news is that this can only reduce the quality of KNSD-HD, the NBC HD channel. Well, at least KNBC still has better picture quality.
