did not try dvd but did connect to coaxial connection with 2 cable boxes . also this is a smart tv and all smart functions worked ok. have video cam connected to Component/Compsite connection, this worked ok
after a long seach for receipt discovered tv is out of warranty. would love to know what the siren is telling me. have seen others reporting this but no one seems to know why. i would at least like narrow problem down to a circuit board that i can replace.
