When i try to convert a standard MP4 to PSP formatted MP4, the conversion process reaches all the way to 98.8 percent, and suddenly stops. Pausing and starting again does nothing. It does this when trying to convert any MP4 that isn't in a PSP readable format. I've tried using various settings with the conversion. I'm using K-Lite codec pack, which was installed before Xvid4psp was installed.
