After studying many post, is does not seem to be clear what could be the exact cause or combination which leads to the (slight) MB on the 1910/2910/3910/ (i am aware only the 1910 seems to be having "bigger" troubles).
In order to pinpoint this somewhat more i am wondering if anyone has confirmed MB from player to his/hers screen, followed by insertion of an independend scaler (testing 480i mainly).
But in the "Shootout" Kris writes:
"It manifests itself on the 3910 with component 480p output, or 1080i digital output.[...] There were no artifacts at all via DVI and HDMI at 480p and 720p. [...] The other resolutions should [must be "showed"?] very subtle signs of the problem using the test material I have used with all the other Faroudja-based players."
So if MB is also present @480i ("other resolutions") a scaler could not help, one would think. Of course when an SDI modded 3910 is available, it finaly could become clear if the MPEG decoder takes part in the MB feast...
