DVDautorefresh is a simple utility I've written. It seems to work beautifully for me, put a DVD in and it swaps HTPC resolutions and refresh rates seamlessly, automatically before my DVD player (TheaterTek1.1) is open. It also uses the NTSC/PAL flag on each DVD and isn't bound to any region assumptions. There are currently two very minor cosmetic issues in the ReleaseNotes and they are nothing to worry about. I think it's ready for for a small beta test If you're interested, please see http://jump.to/dvdautorefresh for documentation and a download of the setup package. Please email be using email@example.com to let me know what you've run it on and how you got on, see the ReleaseNotes link for an idea of what testing I've been doing and format of response I'm looking for. regards, Rob.
