Have you tried the manual option? Turn on your DVD player. Press "TV" or maybe a different button for DVD players, then a red light on your remote blinks once. Then hold both the "up" volume and "up" channel button down until your red light is permanently on. Then whilst holding your remote control 1mm away from your DVD player signal light (usually red too), hold down the "power" button until your dvd player switches off. Then switch it on again and try other buttons. However, I've only tried this on an LG TV, but took me 2 days until I really put the remote in front of that signal light. Took about 1 minute or more while holding down the "power" button. Hope it works =)
