Well, I hear from most of the people that ScriptHook.dll in version point 4 (0.4.0) works well with GTA IV 126.96.36.199, while the ScriptHook.dll in version point 5-1 (0.5.1) works well with GTA IV 188.8.131.52.
Also, just a research, dsound.dll enables logging into a file (asilog.txt), while xlive.dll doesn't, but used to remove Ms. Games for Windows LIVE menu system when in game.
