I HAD a working ASPI layer until I installed AnyDVD on my comp, and I can't figure out why or how the program changed ASPI. Here's the log as soon as I opened Decrypter: I 13:45:24 DVD Decrypter Version 18.104.22.168 started! I 13:45:24 Microsoft Windows XP Home Edition (5.1, Build 2600 : Service Pack 2) I 13:45:24 Initialising ASPI...

E 13:45:24 Reason: Invalid ASPI installation detected It worked fine before I installed anydvd. Should I uninstall it? I really need it for some of these new discss that are coming out such as the Grudge. AnyDVD so far is the only program that has allowed me to successfully rip it. Any help is greatly appreciated. I can switch to Microsoft's SPTI and it works fine with no errors. Do I have really have to have ASPI or will SPTI (SCSI PassThrough Interface) suffice?
