If XySubFilter doesn't show up on the list of filters during playback, it likely isn't installed or isn't installed correctly. Check to see if you installed the 32-bit or 64-bit version. That should match with the 32-bit or 64-bit version of MPC. That is most common mistake made with XySubFilter.

If you downloaded the correct version of XySubFilter, try reinstalling it.
