Advertisements It appears that KNBC and KTLA have added some new sub channels. KNBC has added 4.4. It appears to be an SD version of 4.1, but letterboxed. There is no 4.3. KTLA has changed 5.2 in to some sort of music video channel. Only watched it for a second, but doesn't seem interesting. They moved the spanish simulcast HD channel that was at 5.2 to 5.3. All this would seem to mean that we are going to get an inferior HD signal with all of the multicasting. Why can't they shut off these channels, at least during primetime and sports? Don't they realize what they are doing to the quality of their signal? Anyone in SoCal have any thoughts on this?
