Very insteresting! I didn't even know this thing existed...
I can see "天利" (which is read "tenri" in Japanese, so I suppose this is how you write "Tianli" in Chinese) written in the back of the DVD player.
I am no specialist in Chinese language, but looking at the internet, I found out that the characters for Sega are supposed to be "世嘉".
Can't you find them somewhere in the equipment?
