The MediaFire link for the two .7z files inside a .zip file worked.

The .m2ts and the .mkv look exactly the same on my BD player and they both have significantly more judder than the .mp4.

All three files have a very smooth looking camera pan when played in MPC-HC on my PC, which is connected to a CRT monitor set to 1152x864 with a 75 Hz refresh rate; as judder-free as is possible on a setup in which the monitor's refresh rate isn't perfectly synced to the video's frame rate or an exact multiple thereof. My plain IVTC'd encodes on my BD player are also as judder-free as possible. The only issues I have with those are the sawtooth and moire interlacing artifacts in certain scenes. The same BD player plays DVDs with hardly any sawtooth or moire effects, and my other devices that output a 480i video signal also do so with hardly any sawtooth or moire effects, such as various VHS VCRs, my WD Live TV hardware media player (even when playing my plain IVTC'd AVC files), and a couple of ATSC TV tuner boxes.

MediaInfo identifies your .m2ts and .mkv file as progressive, and the .mp4 version as interlaced, bottom field first. All three of them are 23.976 FPS.
