4.03 is no good for 160x120 because despite the setting it actually converts them at 176x128 which is why they crash so uninstall that. Run regedit and go to HKEY_CURRENT_USER/SOFTWARE/MICROSOFT/INSTALLER/PRODUCTS, one of the numbered folders will be for 3.68 so delete it, then delete the program folder from wherever you installed it. 3.57 should now install. There is no setting in 3.57 for 160x120 so what you have to do is start a conversion with it then stop and close the program.This will generate a file called transformsetup.ini in the install folder. Go to the install folder and open the transformsetup.ini in notepad and edit VWH=160*120. After you have done this it will convert to 160x120. Do not go into settings though or they will return to default just load your video and convert. If you find your converted AMV files give you "format error" when you try to play them on your player go back to the transformsetup.ini and change to VFBS=medium to lower the frame rate.
I find I get best results if I pre-process with VirtualDub, there is a guide on how I set it up
HERE. An additional setting if you are using AMV Converter set to high frame rate then in VirtualDub press CTRL+R and select convert to fps and set to 16. If you are using medium setting in AMV converter set fps to 12.
