AMV Video Conversion to 128 x 160
 

I bought my s1 mp3 player a couple of weeks ago but the AMV converter that it came with only did AMV files in 96 x 96 and 128 x 96 and all the new ones seem to do 160 x 120 but i need one that can do 128 x 160

crazygazza, The 1.8 converters will only do 160x120, most players will rotate the video when played to use full screen. You need to use Version 4.00 of 3.57. For 3.57 you need to make some manual adjustments as posted HERE.
If you player does not auto rotate, no fix for this has been found other than upgrading your firmware to a version that does. However be warned that you could kill your player trying to upgrade and you must make a backup of your original software before you try. To do this you need to download s1fwx from the Download>Tools section and there is a guide to backing up your firmware in the Knowledge Base.
You should also read the Dead Player Recovery Guide HERE so you understand what need to be done if you do kill your player
