I know they added Speed and Versus to the "HD" lineup, while retaining them on the original digital numbers. Later added spike, travel, usa, etc... Then Speed and Versus both went SDV for HD this last June. The digital offerings were still working without SDV, as I used them as backup recordings for both previously mentioned stations. The only analog channels that are viewed are locals and nickelodeon. Don't know about the rest. The Titan TV listing for torrance t/w indicates a full set from ch15 up to ch99. But I know for certain that 49, the weather ch, does not tune on any of my analog tuners. And again; the problem with running out of guide data started after tuning adapter, with standard size HDD. And continues to happen with 2TB dvr_dude upgrade.
