Inspired by your post, I started looking at my PSP setup again, to see how
I could streamline it.

What I want to do is:
1) Record a particular show nightly (two of them actually - The Daily Show
and SportsCentre)
2) Have that show magically appear on my PSP before I catch the bus to
work in the morning.

I'm not finished working on it just yet, but I have successfully
transcoded an AVC file to a format that is playable via the RSS
functionality on the PSP.

My ffmpeg commandline is:
ffmpeg -i "${source}/${infile}" -acodec aac -ab ${audiorate} -vcodec h264
-b ${bitrate} -ar 48000 -mbd 2 -coder 1 -cmp 2 -subcmp 2 -s ${resolution}
-r 30000/1001 -title "${title}" -f psp -flags loop -trellis 2 -partitions
parti4x4+parti8x8+partp4x4+partp8x8+partb8x8 -vlevel 13 
"${target}/${outfile}.MP4"

where my default resolution is 480x272 - feel free to play with the
bitrates etc.

Once that file is created, I drop it into a directory on my webserver, and
have a php script that uses feedcreator (feedcreator.org) to generate an
rss file.  The PSP can then be scheduled to download the feed's videos at
a whatever time I set it, or can be manually downloaded.

I've got all the individual pieces working, I just haven't spent the time
to glue it all together just yet.  If there's interest, I can post my
scripts when they're a little more ready for prime-time - likely some time
next week.
