I've been holding off posting to this thread until we've tested it ourselves, but we've now heard from over 10 customers that have loaded DV Rack on their MacBook Pro using Windows, and it works fine. Here are a couple of notes to be aware of:
1. Windows won't natively read the Mac partition - you'll probably want to get a small utility called MacDrive for Windows, which will ensure that Windows will read and write to your Mac partition, your Mac-formatted CD-ROM's, removable hard drives, etc. DV rack can record to any device with a drive letter, so if you have MacDrive installed, it'll record right to that Mac-formatted removable USB2 drive just fine.
2. The MacBook pointer device only has one button, and Windows doesn't have a keyboard shortcut to right-click like MacOS has. DV Rack uses the right-click for a lot of settings, especially if you are at 1024x768 resolution. You can either use an external mouse (like the Mighty Mouse) or use a freeware program like this one:
