I'm burning some basketball games onto DVD+R for a friend. The capacity of my discs are 4.7GB, and I want to put 2 games on a disc. The 2 games together amount to 4.89GB. Each game is one .mkv file, one 2.48GB and one 2.41GB. How can I possibly shrink the file a little bit so that they can both fit? I have a lot of games to burn, so I really don't want to waste a disc by only filling it half-way if I don't have to. Thanks for your help!
