We still have about 35 channels that are analog only. No simulcast and no HD equivelents. Right now I use an Elite for most stuff, but still have to use a regular Premiere for all the analog channels. We've been using TAs for about 3 years now. The only thing I can figure is that they started using SDV to increase bandwidth for OnDemmand, because we have no got any new channels in at least 7 years.
