I just brought a 40 inch samsung tft-lcd t.v. and i need help in how to get to the dvd screen to watch dvds. I already connected the dvd to the tv. I read the owner's instructions but it didn't say anything about how to turn to the dvd screen. I tried switched to all the channels when the dvd is playing but still the dvd screen don't show up, just the tv channel screen. I also tried pressing all the buttons on the remote too. If anyone who has this t.v or know how please please help me. thanks.
