Kappa21,
Do You mean AMV Converter 3.68, there is no 2.2?
This is possibly to do with the hardware of your player.
You can fix this by installing MP3 Player Utilities 4.00 which you can download
HERE
Once installed Go to the AMV Converter folder and open the AmvTransform.ini in Notepad and change to these settings "BMPADJUST=3" and "CHIPTYPE=0"
Your converted AMV should now be flipped and appear the right way up n your player.
