gos1, If you are using Versions 4.03, 4.05, 4.07, 4.09,or 4.10 then you video is being converted to 176x128 which is to large for your player to handle. Even though these versions have a setting for 160x120 they actually convert to 176x128. You need to use version 4.00 or version 3.57 setup manually as posted here:
