Questions related to Fraunhofer IIS mp3 Stereo eXtended (mp3 SX)

mp3 SX successfully created an mp3 Surround file, but during playback most of the sound seems to come only from the center channel. What's wrong?

The resulting audio redistribution of the conversion process depends on the stereophonic quality of the input mp3 file. If you use a dual-mono-like mp3 input file the resulting output of the mp3 SX conversion will have a dominant center channel.
