RCA DWD490RE DIRECTV/UltimateTV ReceiverSee Restrictions)
Does what it says it will do.
Great product, makes Directv much more enjoyable.  We can now watch one program and record another.  The hard disk recording has the typical disk over tape advantages; direct access without rewinding, instant jump forward, etc.  We're now in habit of recording what we want to watch, then skipping commercials later during playback.  The live re-play is used often also.  And the..price was..less than the local vendor.  Just a great product.  some minuses:  1.) I'm not sure where to get questions answered, though there's some info on the web.  2.) once webtv is connected, it never disconnects.  3.) the disk is constantly writing, I worry about the life of the unit, but that issue isn't addressed in the documentation anywhere.  But overall, we're very pleased with the unit.
