zzyzzyxx, For 160x120 you can use version 3.57 setup as descibed in this post:

which is the method I use.
You can also use version 4.0.
Version 3.74 is an early version of 4.0 so it should work. Go to the AMV Converter folder and open the AmvTransform.ini in Notepad. Make sure the setting CHIPTYPE=1, if it is set to 0 change it to 1 and save. This should unlock the 1.8 screen settings however you will not beable to cahnge frame rate and quality settings.
Version 3.57:
