Sony's RVU implementation should be no different than Samsung's. It's a protocol standard, not an interpretation. Again, back to the same point... DirecTV (and Sony) advertised this as a fully fleshed-out feature, baited thousands of folks to buy these units, only to experience barely-watchable television.
I'm curious why so many here defend DTV when the best course of action would be to make visible the shortcomings so they can fix them?
