Avc

I realized that the PSP refuses to play all my .MP4 files from the root VIDEO folder. If I move them to MP_ROOT/100ANV01 it will work but if I put them in the VIDEO folder PSP says that they are not compatible data. After investigating a little bit, it seems that it only refuses to play AVC encoded files all other are fine. Well, if fact only MPEG-4 320x240 files can be played from the video folder whereas AVC 480x272 is fine if I put them in MP_ROOT/100ANV01. Another interesting fact is that if I encode the files using Media Manager for PSP 2 instead of 3GP converter then I can play AVC files from the VIDEO folder.

If you’re new to the PSP you must remember when copying files video files (created with 3GP converter or PSP Video 9) to your PSP that M4Vxxxxx.MP4 files go to the MP_ROOT/100MNV01 dir of the Memory Stick and the MAQxxxxx.MP4 files go to MP_ROOT/101ANV01 dir. M4Vxxxxx files are conventional MPEG-4 files and MAQxxxxx are MPEG-4 files using AVC codec (recommended).
