I think itīs a change in the a build, that itīs included with the .exe . So you donīt need to install the plugin anymore. Maybe because you installed the plugin.... you have 2 entries. I canīt remember, with build it was, but I believe that there was st like "Encluded tempo and pith to the dsp studio".
Maybe itīs a newer version than the plugin.
Modify:
Look at this
12.0.133 (12/15/06)
1. Fixed: Misspelled the word 'Swap' on DVD properties.
2. NEW: Tempo, pitch, and rate DSP included as a default DSP.
3. NEW: Tempo & Pitch plugin nicely handles 4.0 and 5.1 sound.
4. NEW: Added "Rate" to the Tempo & Pitch plugin. (discovery: Bon Jovi at +0.3x = Stevie Nicks)
5. Changed: Tempo & Pitch plugin frees all resources and doesn't touch the input data when enabled with all sliders at +0.00x.
6. Changed: Made default DSP Studio studio pages more visually similar.
7. Fixed: Could not start playing TV in Theater View.
8. Fixed: Playback time display wouldn't nicely handle DSP plugins that changed the length / rate of playback.
9. NEW: Tapping "Pause / Break" in Theater View will loop through on screen status messages. (draw speed, some video card capabilities, etc.)
10. Optimized: Several Theater View optimizations to improve draw performance and lower CPU usage. (<5% CPU usage is typical with a modern video card)
