Hi Torpedo,
I tried all three of them, first with RAD Video Tools, then in SH5. Only the 4:3 version looks right in SH5 on my 16:9 monitor, the other two look distorted, squashed horizontally -> everything is too thin. In the 4:3 version they have correct proportions. Your own monitor is 4:3, maybe that causes some confusion? Anyway, here are some screenshots for comparison:

What tool/utility did you use to make the 4:3 version?
