Hi Smoulders
The music files are not held "inside iTunes" as you seem to believe, but rather iTunes is simply linking-to/playing-back files on your hard disk.
Rather than trying to import the iTunes library file, you need to work out where all the files are actually stored, and add those locations as import folders in MC.
Also, it's worth noting that the actual files hiding behind the iTunes library are not necessarily all stored in the same location on your hard disk.
For example, if you bought all the music from iTunes Store, it's likely the files are stored in the standard folders below:
Windows XP: C:\Documents and Settings\username\My Documents\My Music\iTunes\
Windows Vista: C:\Users\username\Music\iTunes\
Windows 7/8: C:\Users\username\My Music\iTunes\
However, if you already had a large collection of music, and it was simply imported it into iTunes from its existing location, this music could well reside elsewhere.
If you are struggling to find them all, simply do a search of your computer e.g. looking for all mp3 files:
- press win+E
- select "computer" from the tree view on the left
- press F3
- type *.mp3 in the search box
- hit enter
After a while a list of search results will pop up, and a quick scan of the rows should show you where the music is stored.
Find the common root folder(s) for all these files and add them to the MC import.
The jitter will likely be harder to track down / resolve, but a good place to start is ensuring it's configured correctly in MC.
Under Tools > Options, select Audio on the left:
As a good starting point select:
Output Mode: WASAPI - Event Style
Output Mode settings: Select your DAC from the device list and make sure "Open Device for exclusive access" is selected. Leave the "Hardware buffer size" at 100ms
DSP & output format: change "output" for anything above 192KHz to 192Khz, and at the bottom of the "output format" page, select the correct Bitdepth for you DAC (32-bit)
The fact your DAC is 32/192 capable, I assume you have had to install drivers?
If so, it may be that you are better off using ASIO as the output mode, but give the above a go first.
