Comment (by ctreleaven@…):

 No.  Myth includes a .gitattributes file that causes another file to be
 updated during a git-archive operation.  Which is what happens when GitHub
 creates a tarball from a commit hash.

 Unfortunately it apparently creates different results at different times.
 The following shows the difference between the Sep 17 snapshot and Sep 25:

 Just one line...but more than enough to mess up the checksums!  I don't
 understand git/.gitattributes well enough to determine why.  I contacted
 the MythTV dev who set this up (2 years ago) but he stopped responding
 (IRC) and I believe he is leaving on an extended trip in the near future.
