I don't know where to point you. The reviews of the SA8300HD are split between those that get SARA or Passport software and I don't know what software type you would be getting. I would recommend looking for your local AVS forum to talk to people in your area and see what experiences they have with the box.
I personally didn't care for the box for several different reasons. It did record the shows I told it to most of the time, but there were user interface problems and other quirky problems.
