DVD Genie allows you to modify the region code for popular software-based DVD players such as Software Cinemaster, PowerDVD and WinDVD, and others. It also allows you to tweak these programs with undocumented features to better fit your system.

DVD Genie also allows you to select which program runs when a DVD disc is inserted into the drive and contains support for full screen zooming on wide screen movies with certain players. (description from tweak files)

I have used DVD Genie for about a 3 months with no apparent problems. Although my set up is supported by DVD Genie you do get the feeling that this quite a good reliable product.
Auto region selection, multi dvd player support and auto loading features.
As a free download I think it's worth a try.
