What's the best bitrate & framerate combination for 1080P playback using external media players?

To my surprise, my JCMatthew media player (using Realtek chip) refuse to play my MP4 files (1080P60 24mbps & 720P60 18mbps). It says "Invalid File". Another media player using the Boxchip F10 also fails to play. Only the GIEC GK-HD-110 plays them smoothly. However, when played on i3 laptop and connected to HDTV via HDMI, the files played flawlessly.

I produced an alternative M2TS file (1080P60 24mbps) and it plays, but stutters. Some parts of the background music cut off abruptly and there is jerkiness between scenes.

Is the framerate or bitrate the main culprit here? Which of the two to sacrifice (downgrade) is preferred?

For forum members who have produced Full HD videos for external media player playback, what is your recommended maximum bitrate & framerate choice to guarantee smooth playback.

PS: I would be grateful if anybody knows the Realtek chip model used in the JCMatthew MP1100 player. The product is so mysterious with no chipset info. I bought it 2nd hand. I believe the chipset used is inferior to the Realtek 1077DD (as in the GIEC), otherwise my player would have played successfully.


Secondly, I recant what I previously said about AVC H.264 being better quality than MP4. Maybe because of higher compression used, the MP4 actually looks better (same bitrate & framerate comparison).
