It's worth noting the DVD genie only works with drives that are region free..
DVD playback requires both the hardware (drive) and software to have the right region, or be region free.
Most DVD drives will not be region free out of the box, but many can be made region free relatively easily (lite-on drives are so simple it's silly), which just leaves the software side of things, which DVDGenie does.
There are some programmes that manage it purely in software by fooling windows in regards to the hardware.
