ADD ON TV TUNER FOR PORTABLE DVD PLAYER

First, you'll probably get more response if you lay off the caps ... all uppercase equates on the internet to shouting,and is considered rude.

As for your question, devices of the sort you seek are common. If your portable DVD player has standard RCA-type input jacks for video and audio, you could use any of a variety of stand-alone outboard TV tuners designed primarily for automotive/RV video applications. Such devices are made by AudioVox. Pyle, Sony, Pioneer, and Kenwood, among others. You should have no trouble finding the critters at any etailer or retailer that has a good selection of car audio.
