MP4 is the container, it is the same for psp and others.
Content matters:
PSP has some restrictions:
- Resolution (up to 480x272 and fixed 720x480)
- AVC Level and Profile (Level 3.0, Main Profile, not High)
- count of ref and bframes (2 ref, 3 b)
- some other encoding options (no b-pyramid)
- Audio: LC-AAC Stereo (no HE, no 5.1)
So for example you can't play a MP4 with 1920x1080 AVC Level 4.1 onto a PSP
