Movies2iPhone is available for Windows and Mac OSX, pick up the one that fits your needs.
Compatible with Windows Xp, Vista and Seven (32 & 64 bits).
Compatible with MacOSX Lion (10.7) and Mountain Lion (10.8).
After releasing Movies2iPhone 1.24, I had to drop support for older version of MacOSX. If your Mac is runing under an old system like Leopard (10.6) or Snow Leopard (10.7), you can still enjoy Movies2iPhone by downloading this older version.
