I still have that machine with DVD-o-matic on it,
so I recently did
it again with the same setting, and it turned up again.
Today I installed a recent version of DCP-o-matic on the same machine
and did the same scene with it, using same source file, scaler,
REC709 preset, datarate setting, etc
[snip]
I'm fairly sure that DVD-o-matic had incorrect REC709 conversion
matrices for a large part of its life (maybe all of it...) so I think
that would explain it.

Carl
