You could use convert (part of the imagemagick package) to convert
jpgs or other formats into mpg. They also use mpg2enc, but you don't
need to write your own config file. I have tried it with some images,
but it doesn't work with all of them. With have to see what we need to
fix in the driver. You will also have to use images with supported
resolutions, or use the -size option of convert.
It works if I create a jpg with gimp (size 702x576) and use 
convert test.jpg test.mpg
