2.0.1-Win7 | Distorted sound Digital Clipping

[singul4r1ty]

I just did a standard upgrade a week ago to 2.0.1;
and now the sound in mpeg4/mp4a videos I play is distorted in the lower frequencies (basses)
like its constantly peaking causing rumbling noise.

Opening the same video in Windows media player gives no audio troubles.

[VLC_help]

Does Tools -> Messages (set Verbosity to 2) complain something during playback?

Following warnings generated by an mp3 (mpga encoded) which has same distortion:

Ok so I did some google-fu with the log warnings started with upsampling into nyquist sampling
into Anti-Aliasing filter http://en.wikipedia.org/wiki/Anti-aliasing_filter
into digital clipping http://ubuntuforums.org/showthread.php?t=820766

So if you keep the volume level below 145'ish in VLC you will get no digital clipping/distortion, apparently the volume range in VLC is from 0-200% which I hadn't noticed.

I do miss an options to change the maximum volume scale in the VLC options, because of possible distortion I want to cap it to 140%.
