Same issue with a White Westinghouse 26" LCD w/ integrated DVD player. Will accept DVDs but gives a "loading" message and then says no disc but if you hit eject it will eject it. Know it is not the DVD, as we even tried those that used to work on it. The unit is garbage but what do you expect for the price point? Something that worked more than a dozen times? It is all Chinese crap. Shoddy engineering, shoddy supplier base, shoddy assembly...
Oh yeah, forgot that when I went to mount it, one of the mounting lugs simply snapped off with little force.
