I'm looking to burn a game to a disc and I can't find a re-writable DVD that has enough space. I know they make them in dual layers that have 8GB, but I can't seem to find them. I've been to Walmart, Best Buy, and a few local computer shops.

If anybody would know where I could find them that would be great. If there is a spot online I can buy them, I'll take that too. Thanks.
