PG-13 Version?

Anyone know where I can find a copy of the PG-13 version on DVD of the movie? I've heard they were released in rental copies, and I assumed/hoped they would be from Blockbuster, but I wasn't sure, they've since closed down, and I don't know where to look for one to buy, perhaps besides random used DVD stores. Anyone possibly have any ideas that could help at all? I really don't know where else to ask. Don't know why they didn't just release the version on DVD in the first place. Any help would be appreciated. Thanks.
