basic PMP Mod AVC FAQ by madruscoe:

-----------------------------------------------------------

What to do with these files/folders? Where to place it?
- If you are running SE or OE firmware, place 
  "__SCE__PMPMODAVC" and "%__SCE__PMPMODAVC" to 
  \PSP\GAME150 folder on your memory stick (or set kernel 
  to 1.50 and put it in GAME folder). Otherwise (running 
  1.50) place it to \PSP\GAME.

Where to place video(s)?
- To \PSP\VIDEO

My videos not playing...
- Make sure you use PMP AVC videos (encoded) and NOT PMP 
  2. Files are allowed tohave extension .pmp or .avc.

So what application shall I use for encoding?
- Personally I use and recommend you XviD4PSP having 
  plenty of setting for encode (like cropping etc.). Of 
  course you can use any encoder you like which support PMP 
  AVC. Anyway the encoding take pretty loooong time (6 fps 
  on AMD Duron 800 MHz, 20 fps on Intel Celeron 1.7 
  GHz...). If you are not so experienced with encoding 
  video see some guide at this forum that helps you get the 
  best video quality ;-). Another supported tool is 
  AVItoPMP.

Subtitles?
- Yes. At first, if you need some special character 
  encoding, delete font10.f (in __SCE__PMPMODAVC folder) 
  and rename for example font10_centraleuropean.f to 
  font10.f. (You can make your own font, see raphael’s 
  devblog and get latest FontGenerator).
  If your movie title is "Movie ABC.pmp" then I recommend 
  you to name subtitles "Movie ABC.sub" or "Movie ABC.srt" 
  to work correctly.

-----------------------------------------------------------

Analogue stick in filelist:
- up/down = up/down
- left = exit
- right = play

Headphones/remote control in filelist:
- forward = down
- back = up
- play/pause = play

-----------------------------------------------------------

Thumbnails are .png files with resolution 96x54 px. They 
can be created on pc and correctly named (movie.pmp, 
movie.png...) but when .pos file are generated, png will 
be overwritten by new screenshot.

-----------------------------------------------------------

to-do/plans/ideas:
- better interface (gui), graphics (I have no much time :()
- analogue pad/remote control support during video play (?)
- standby support (?)
- playlist

-----------------------------------------------------------

Reasons why to use PMP Mod AVC:
- PMP Mod AVC runs 120 MHz so you can play videos longer 
  (than with 222 MHz)
- subtitles can be placed as a separate (.sub) file so you 
  can during playback switch color/font... turn off/on them
- support for more than one audio stream
- support for possition - playing starts from time you last 
  stop the video even when you turn off the psp
- no need flashing your psp to enjoy the full resolution
- volume boost can the audio make louder

Why to use MP4 AVC in 3.03 OE:
- you save about 15 second (no reboot of psp to load 
  homebrew) but lost some time looking for the possition 
  you last time stop your video (not standby but turn off 
  psp) and even hours cause of the processor frequency
- user interface may look better for you
