Shuttering MPEG HD - BUG?

Question

We are using Adobe Media Encoder for encoding video files to our prefered codec. (MPEG HD - .TS) This used to be no problem. Since a few months (november 2013?) we get only video files with shuttering pixel every second. We didn't change the preset and for testing we used the same source files as before.
Does anyone has a solution?

Did you ever resolve this issue?
We're having the same problem since updating to CC 7.2. All was good in CC 7.0. We still have 1 machine with 7.0 on it, and it encodes the MPEGs nicely, but the same setting in 7.2 gives us the Pixelation flash every second or so.
