Mencoding with hardcoded subtitles: subtitle image is negative

If I try to use mencoder to encode an existing MKV file with VobSub? subtitles to a new file with hardcoded subtitles, the subtitles in the resulting file are negative, i.e., the core of the characters get gray (or black, depending on the original vobsub color) and the border gets white.

This happens with many different codecs. If doing the conversion directly from a DVD image, things apparently work correctly.

I have attached an example. The original mkv file was encoded with mencoder and muxed with mkvmerge.

A tip if someone is facing the same problem: as a workaround I started doing something like

mencoder -o outfile.avi -noautoexpand -vf eq2=1:-1,expand=::::1,eq2=1:-1 -sid 0 infile.mkv

Results are far from perfect, but acceptable.
