Are RCA DRD435s covered under the protection plan? I have 3 card-less ones laying around I would like to put to use but I don't want to "invest" 20 bucks a pop if they aren't covered. I also have couple Samsung receivers without any cards. Are those brands covered or is it just D/R/HR - X00 series? Thanks Later note: I did have the cards that originally went in them, but I figured they were worthless since they were from another account and took them out.
