COOKEVILLE, Tenn. -- The family of a 10-year-old girl who received an MP3 video player for Christmas was shocked when it found the player was loaded with explicit songs and pornographic movie clips.

Cookeville resident Daryl Hill said his daughter was thrilled to find that Santa had left an MP3 player under the tree -- until she turned it on.

"Within 10 minutes, my daughter was crying," Hill told Nashville, Tenn., TV station WSMV.

There were video clips of XXX-rated sex scenes and the pornography on the player.

"I wish I could take the thoughts and images out of her head," said Hill.

The Hills had bought three MP3 players for their children that came from a Wal-Mart store in Sparta, Tenn. It turns out one of the MP3 players had been returned to the store from a previous owner who loaded sex clips, graphic war scenes and lyrics about using drugs.

The Hills want to know why Wal-Mart would sell used merchandise as new in the first place, which is in violation of its own policies.

"If they want to be a major retailer, they need to act like it," said Hill.

The manager at the Sparta Wal-Mart declined comment on the matter and referred WSMV to Wal-Mart's corporate office.

A Wal-Mart representative e-mailed WSMV confirming that stores are not supposed to return opened packages to the sales floor. They said they are working to get to the bottom of the problem.

The Hills said they have declined Wal-Mart's offer to replace the MP3 player. They've already bought their daughter a new one and are hanging onto the controversial one until they talk to a lawyer.
