1. SPTI and SPTD are two different things. The first, SPTI, is part of the windows calling interface, and the contemporary "best" way to directly interact with devices at a low level. The latter, SPTD, is a 3rd party interface installed by several different products, but not by dbpoweramp. It is the latter that can sometimes cause problems with ripping software.
2. The link in a post above to the duplexsecure site gives instructions on how to either disable or uninstall SPTD. Follow these if you suspect STPD is installed and suspect it might be interfering with device operations in non-STPD applications. Note that this might break the software that uses STPD (if installed) such as virtual drive, dvd ripping and game-disc freeing software.
