BENTONVILLE, AR -- About 4.2 million Durabrand DVD players sold at Walmart stores are under an expanded voluntary recall.

The Consumer Product Safety Commission says the players' circuit boards can overheat, which might burn consumers or cause fires.

The players come in silver, pink and purple, and sold for about thirty dollars.

A similar recall two weeks ago was just for the silver model.

People who own any of the three models can return it to any Walmart store for a refund.
