mp4 encoder

i cant seem to find a 3rd party encoder that converts .avi to mp4 in 240x432 format.  most encoding softwares that i've encounter have a drop down menu with preset settings for different devices like pda or psp and it does not allow you to enter your custom resolution setting.

i have used the samsung's included media manager, but it is too slow in converting a file.  also, on one of the movies, it did not encode sound for some reason.

anyone using a speedy 3rd party software that has customizable resolution setting for instinct?  if not, what setting do you use to convert movies for instinct?  320x240(pda)??

so when u use preset resolution for psp, does the movie play in full screen without any noticeable distortion?
