 If you looked at a widescreen and a fullscreen video, the original display size is actually the same: 720x480.  They are just stretched differently based on the aspect ratio.
+=== archives: Convert image to video ===
+<code>
+ffmpeg -i snapshot.jpg -sameq -s 720x480 video.mp4
+</code>
+That will create a one frame video.  Then I copy it to about 200 frames to make a 6 second video.
+Avidemux has problems opening a single frame file, so create a long MP4 before trying to create a VOB to burn to DVD.
+=== archives: PSP Format w/ffmpeg ===
+Finally found a working solution:
+<code>ffmpeg -y -i 101._The_Force_Phantom.mkv -s 320x240 -ar 24000 -r 29.97 -f psp -title "The Force Phantom" M4V12345.MP4</code>
+You *can* encode to 480x272 (or 270) and it will playback fine, but for some reason the title tag won't be read anymore.  Seems to be a PSP bug, since a video I downloaded (SWTFU stuff) also won't display it.
+Also, MV1234.MP4 is the old supported format.  My PSP (firmware >5) supports "movie.mp4" naming scheme, as well as folder structures just fine!
+=== archives: Muxing to Matroska ===
+ffmpeg seems to have issues creating MKV files.  For one, they are much larger
+than an AVI with the same encoding options.  Secondly, they dont' seem to work
+well when AC3 is placed in there.  I'd recommend encoding to AVI (or MP4) and
+then using mkvmerge.
