I have a separate ffmpeg binary I built on my backend box to encode for
PSP. My approach was to write a very simple shell script and define it
as a user job. I just turn on that user job for any program I might want
to watch on my PSP.
Here's the script I use: (No laughing, I said it was simple! I'm lazy!)
# MythTV user job to transcode a copy for Sony PSP
/in/ffmpegpsp/ffmpeg/ffmpeg -y -i $FILE -title "$TITLE" -bitexact -f psp
-s 320x240 -r 29.97 -b 384 -acodec aac -ac 2 -ar 24000 -ab 32
Of course, the directories needs to match your locations. I doubt mine
will work for you, ;)
I did briefly have another line in the script to use the ImageMagick
convert utility to copy a resized JPG version of the PNG thumbnail for
the PSP, but I stopped that as I don't care enough. :)

I didn't bother with nuvexport at all, the user job mechanism can pass
the title and filename, and it's all automated just the way it should
be. User jobs rock, by the way!
The ffmpeg development versions have some PSP support, but I did this a
couple months ago when it was easier to use the MobileHackerz tree. I
haven't looked lately to see what the current status in the ffmpeg CVS is.

A quick google for "psp ffmpeg" turns up tons of info, including sources
and build howtos. I got my source that way and built it on my AMD64
SuSE93 box without any trouble.
Here's a link I found in 10 seconds of googling:

I'm running SuSE93 on AMD64 with PVR500MCE. I've had this PSP user job
for a handful of programs working fine for a couple months or more.
