Sjerby, It looks like your player has a 1.8 inch (160x120) so you need to use version 4.0 or version 3.57. Version 3.57 needs to be setup as posted here:

Versions 4.03, 4.05, 4.07 are all designed for players with screens 2.0 inches plus. Although there is a setting for 160x120 the AMV is actually encoded at 176x128 which is to big for a 1.8 screen
