tkarami , you can use
VirtualDub to pre-process your dvd movies.
But note that since it is a widescreen dvd, after conversion to preserve aspect ratio, you can't expect the movie to cover the full screen resolution on your player.
You can use the crop filter to cut out unwanted areas of the movie, and the resize filter to change it to a suitable resolution for your player.
After processing, use the AMV converter provided in the cd or from the downloads section to convert the processed video in .AMV format.
Hope this helps.
