Considering that they will look better with DirecTV, it matters.
these days with the Hopper that isn't true at all. Before I unplugged the D* equipment, I switched back and forth between the Hopper and the HR24 via the same AVR to the same 73" DLP and cannot see any difference at all. And there are many, many others reporting the very same thing.
Guess you'll need a new line of BS to wave your pom-poms about!
