Well, that's unfortunate.  Thanks for clarifying, though.

It would be nice if, when time permits, a similar test can be made,
using the same criteria (encoding parameters, etc.), but with known
clips (e.g., from derf's collection, which has everything, including
both SD and HD clips).  Publishing the versions and exact encoding
parameters (including command line usage) would be helpful to that aim,
I suppose.
