Hey! I'm pretty new to mac, my macbook is a Mac OS X version 10.6.4. It has been suggested to me to download some stuff like "divx" (I followed the link on the Apple site). The download was successful-but I can't install it. I dragged it to the application section of Finder. I tried to open it and it gave me a list of "preferred applications" to open divx with. The choices didn't relate at all-so I picked one at random (itunes) since I couldn't open it otherwise. Now whenever I click on divx, itunes pops up. I know that I have the option of changing which application I want to use to open divx with..but I still end up in the same boat. The same issue has come up with other stuff I've downloaded. What application (if at all) should I use to open divx with? I'm not the greatest with computer stuff and the answer is probably ridiculously easy, but I'd appreciate any help. Thanks!!
