Hello I want to install an application from an original DVD installer, but my macbok pro spits out the dvd every single time. The drive is not broken, because it reads everything else. I don't have an external dvd drive, but I do have a G5 iMac with Tiger. Can I use the iMac to install the application to the macbook pro with Leopard? The application on the DVD, however, is not compatible with Tiger... ty!
