  according to the entity &epsi;  MathML 2.0 Second Edition and first edition are identical.

 Since epsilon is a very frequently used symbol I could not realy belief that what I saw ;-)

There used to be a problem with the various names for epsilon in the spec, and I believe it was only corrected when MathML 2.0
Second Edition came out.

But you are correct that MathPlayer 1.1 is out of sync, and doesn't properly recognize &epsi;.  We have fixed this in MathPlayer
2.0, which is nearing the end of beta testing and should be released in a few weeks.
