I recently converted a .avi to .mp4 with the H264 format (took ages). I was sad to discover that the converter had streched the movie vertically, removing the two black bars. Therefore, everything is streched and people get extremely thin. Now I ask, is it a way to add the two black bars again using a homebrew video player? VLC for PC has several format options, something similar for the PSP had been awesome.
If it exist (or not), please tell me!
