DVD rewind help?

I just bought a DVD player and got a Blockbuster member ship and rented my first movie yesterday and now I want to return it but I can't find a rewind button anywhere on my player and the instructions are worthless.
Can anybody please help me? I don't want to get charged that stupid $2.00 rewind fee.
Update: Thanks so much guys, I'll try it!

I just can't believe they don't have a button to press.
