PSP Go & MP4: No Native Support—Conversion Required

Format Incompatibility

The PSP Go does not play MP4 files natively. It uses Sony's proprietary PSP Video (PMF) format.

Solution

Convert MP4 → PMF using third-party conversion tools. Search for "MP4 to PSP converter" or "MP4 to PMF converter" to find current options (HandBrake with custom presets, PSP Video 9, etc.).

Ensure output settings match PSP Go specs: 480x272 resolution, H.264/AVC Main Profile, AAC audio.
