I worked on that project and designed the feature to embed an MD5 of the WAV audio payload based the similar FLAC features. Thus the MD5 of the FLAC header and the MD5 of the BWFMetaEdit MD5 feature will equal between a PCM/WAV and lossless FLAC version. Still the MD5 chunk in WAV, as used in BWF MetaEdit, is not standardized beyond what was included within the project.
No disagreement with the "bit problematic" review but please report issues at http://sourceforge.net/p/bwfmetaedit/bugs/ so that they are known.
