Got a Mac iPod from friend, how to transfer to Windows 7??

I got a iPod from a friend of mine, but it's a Mac format iPod; I have a Windows 7 non-mac computer. I like the music and all that is on the iPod, but I am not sure how to format the iPod to my computer. I have tried a couple programs that I have seen that say it is possible, but nothing is working. One recognized the iPod as a Mac format iPod, but I don't have a Mac computer. iTunes on my computer doesn't recognize the iPod because of this, as well. How can I format this iPod to my computer or at least have it recognize it? I have some music on my computer that I want to add to it as well, but until I can get the iPod to recognize my computer and computer recognize iPod, i am lost. Any help would be helpful. thanks.
