First question: What's a modulator? How old, and what brand, is the TV? Did you go to "Source/Input/" to select the input for the DVD?
OP was using a analog RF modulator which takes the analog composite video and analog audio and creates a analog TV channel (IE modulated RF channel).
Then the OP connected the output of the modulator to the TV antenna input.
To get the Analog RF channel to show up on the TV the OP would need to set the TV to "AIR" or "ANTENNA" in the setup menu. Once the tuner has been set to "AIR" or "ANTENNA" they should be back to normal. But if they had rescanned the TV with the modulator off it may have been removed from the channel list and the OP would need to either manually add the channel or do a rescan with the modulator on.
Slight possibility is the OP may have connected the modulator incorrectly (IE antenna on the RF output side and the TV to the Antenna input side which could explain why they are not seeing the DVD player.
They are not using analog AV inputs if they are using a modulator, only the RF input of the TV.
