When you encoded the video, was the encoding mode in TMPGEnc set to "3:2
pulldown when playback" [sic] and the frame rate set to 23.976 fps? Other
settings won't work when your source is film-rate NTSC. Video encoded this
way plays just fine on my Apex AD600A, which is an older player than yours.

TMPGEnc provides a preset file, "SuperVideoCD (NTSCFilm).mcf", that sets
this option correctly. I usually load that file, load "Extra\unlock.mcf",
and then make changes to those settings.
