Still can't crop 4:3 to 16:9 with ffmpeg engine

[csdesigns]

Source file is Photo-JPEG (have tried MJPEGb and MPEG-4 as well), 640x480 letterboxed (4:3). When I attempt to do an encode using ffmpegX to XVID (.avi) or MPEG-2 (.mpv) using the ffmpeg engine and cropping the letterboxes off to a 16:9 movie, the resulting video is only scaled to fit in a 16:9 frame. Thus, I am left with large black boxes on the left and right. The console log reports no errors and everything indeed seems fine with the encoding otherwise.

Major, you said this was an issue with dual processor systems previously (I am on a DP 1.25GHz G4), but that you didn't know where the problem was stemming from exactly in order to fix it. I have also tried encoding on a 433mhz G4 (upgraded iMac Rev B) and the video output was the same as from the DP G4, so I doubt this cropping issue has to do dual processors only. I am using the latest release with all of the latest libraries. Anyone have any suggestions/tips/work-a-rounds other than cropping with an app like Compressor or Cleaner first? Thanks for any help you can provide.
