The placeholder %\_md5audio% on export produces different md5 hashes before / after any kind of tag-editing of ogg files (doesn't meter if the size of tag is changing or not). Tried only in v2.40 and v2.41 (don't know if exist in earlier versions), on WinXP sp2 and sp2c.
I mainly use ogg, mpc and mp3, so another kinds were not tested (and all the tests were very simple).
Codecs:
Vorbis (Xiphophorus libVorbis I 20010615)
Vorbis (Xiphophorus libVorbis I 20010813)
Vorbis (Xiphophorus libVorbis I 20011014 (GTune 2))
Vorbis (Xiphophorus libVorbis I 20011231)
Vorbis ([Xiph.Org](http://Xiph.Org) libVorbis I 20020717)
Vorbis ([Xiph.Org](http://Xiph.Org) libVorbis I 20030308)
Vorbis ([Xiph.Org](http://Xiph.Org) libVorbis I 20030909)
Vorbis (AO; aoTuV b4b [20051117] (based on [Xiph.Org](http://Xiph.Org)'s libVorbis))
However, all the 1200 ogg files used for testing are VBR Stereo.
