I undrstand that the latest version of Ri4m, version 126.96.36.199 Beta, which just came out, corrects this problem.
Version 188.8.131.52 BETA (9 March, 2007)
Added code to detect whether the DVD appears to be protected. This is displayed in the main window during Step 1.
If the DVD isn't protected, there's a new button in Step 1 to open the DVD with DVD Shrink directly.
Attempted to fix the "Not a DVD" problem that some users have had in 184.108.40.206. If that still does not work, post the debug log you get during Step1.
RipIt4Me now terminates AnyDVD "the right way" (by sending a WM_CLOSE message to its main window in the tray, instead of killing the process).
Added "Open .ini file" to the Main menu. This required adding two strings to the language file.
