There is still alot of guesswork as for the PSP Media File format (.pmf). One guy was able to make a few, but I think someone said something about him having access to the official PSP Dev Kit to make them. That, and there is no ATRAC3+ codec out, only the standard ATRAC3.
Give it time... It'll happen.

Firstly I'm no expert on this but here's something I've played around with.
Files on a UMD have a .MPS extension. The files are found to contain H264-ES by mplayer. If you dump the files you can try to use mplayer to dump the video on the .mps files. (don't bother doing the main movie it's big)
On the UMD I was playing around with there are a few smaller files, which are the previews of other movies and the Sony startup clip.
I tried mplayer -dumpvideo on all the small ones and the video doesn't play.... EXCEPT on the Sony startup clip. You can spot that one because it's 2,768,896 bytes.
The video dump of that one did play back in mplayer:
Playing stream.dump.
H264-ES file format detected.
FPS seems to be: -378614/10000
================================================== ========================
Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family
Selected video codec: [ffh264] vfm:ffmpeg (FFmpeg H.264)

Audio: no sound
Starting playback...
VDec: vo config request - 720 x 480 (preferred csp: Planar YV12)
VDec: using Planar YV12 as output csp (no 0)
Movie-Aspect is 1.82:1 - prescaling to correct movie aspect.
VO: [directx] 720x480 => 872x480 Planar YV12
As you can see it's an h264 file, so we know that a 1.5 will play h264 if it's on a umd in the correct format. It's also interesting to see that size of the video is 720x480 which is DVD resolution if I remember correctly. So far none of the other files will dump video. Encrypted I guess.
[edit] Elecard will demux all the videos.
I'm playing around now to see if I can manage to encode an h264 video and mess around enough to get it to play from an emulated UMD. I have already tried ripping out the main movie, changing some filenames around and emulating the UMD. Start the movie and you get the one of the previews playing instead. Maybe this will spark some video experts grey matter into finding the correct headers and stuff to add the the h264 video to get it to play...
