Ok, I have been using the following to rip/burn DVD;s
O/S: W2K
External DVD-R: Sony DRX-530UL
IEEE 1394 PCI card: Adaptec Firewire Card
Ripping Software: DVD Shrink 3.2
Burning Software: Nero 6.1 Ultra
Media: RICOH-JPN / CMC-MAG

My success rate using the above method has been about 95%. In those few cases where decryption failed with DVD shrink, I tried to use DVD Decrypter 3.2 to rip the DVD and then use DVD shrink to compress them. When I open up DVD Decrypter and try to decrypt, i get the following error: "Cannot read from file: VTS_01_2.xxx" and the reason states is "DVD Drive has not been authenticated". When I try to authenticate, i get the following message: "ASPI Manager was not found on system". Ok, what I don't understand is, since I am running an external device (my sony DVD-R) via an IEEE 1394 PCI card, what difference does it make what ASPI drivers I do, or do not have?? My understanding is, that the advanced SSCI programming interface drivers are essentially drivers which enable programs/hardware to communicate with SCSI and ATAPI devices, such as internal CDR-W's, DVD-R, etc. Since I am accessing my DVD-R via a IEEE 1394 device, why is the ASPI driver issue even a problem?? Why can't DVD Decrypter interface with my DVD-R via my IEEE 1394 card without my ASPI drivers being a problem?? I can't find any info on this, except that I need to download ASPI drivers (take your pick, from NERO or microsoft, etc). My PC is currently running fine and I would rather not screw around with downloading any addtional ASPI drivers. Can DVD decrypter work with an external DVD-R via a IEEE 1394 device??? Thanks in advance for any help.

Windows 2000 comes with the built in SPTI interface but does not come with a ASPI Interface.

Are you running as an administrator? These errors could be caused by not using an administrator account when using SPTI.

Note that only members of the administrator's group have the correct authority to send SCSI pass through requests. Users without administrator authority typically fail either CreateFile or DeviceIoControl with ERROR_ACCESS_DENIED (5L).
It is probably a good idea to install a ASPI interface.

Then you can choose which interface to use in DVD Decrypter.
Tools > Settings > I/O tab.

You would probably not have this problem if you were using ASPI because it probably does not need to be used from an administrator account.

Ok Veblin, thanks for the info. I do log in as administrator, using W2K, but the SPTI interface does not get along (apparently) with DVD Decrypter. Thanks for the link to ForceASPI. It seems that if I want to use DVD Decrypter, i MUST have a working ASPI layer. Period. So, I guess I will break down and install the drivers from forceAPSI (it appears that these are scripts that you run as batch files from a CMD prompt. Can someone vouch for these files/scripts???? ) As i stated in my original post, I am always a little leery of adding/replacing/deleting drivers, patch files, etc. Not that I will not do this, but I always prefer to do as a last resort........
