Here's an info update on the Tracstar SV-360, in case any are still following this thread. There is an add on piece of hardware (available from Tracstar) called the "110 Adapter" that will allow HD reception with DirecTV. This adapter is only required to receive HDTV signals from DirecTV, with Dish HDTV programming can be received via the SV-360 with no modifications as long as you are a subscriber.
