You have a more safer “aggressive mode” as default. It will be even a little safer in the next version.
The “Safe Mode” is the “good and clean” mode as it always was (same as the default mode in 22.214.171.124)
I found a very good compromise between compatibility and system stability:
AnyDVD “aggressive mode” now has both layers “aggressive” and “safe” always working at the same time.
The “Safe Mode” layer is still active if “aggressive” is enabled, and every IRP (I/O request packet) processed by the safe mode layer will be tracked. The “aggressive mode” layer checks, if an IRP has already been processed by the “Safe Mode” layer. If it is, “Aggressive” won’t do anything.
If an IRP is not processed by the “Safe Mode” layer, e.g. a program with a “not well designed I/O subsystem” like 1-click-dvd-copy (no, I didn’t say this is bad software!) sneaks in I/O requests directly to the port driver and not passing it to the class driver as Microsoft suggests, “aggressive mode” i/o will catch and process this IRP.
