Samsung F series - Thumbnail aspect ratios

[Dillster]

Gents,

I currently source movie covers in a 200x300 px size - ie it looks like the cover of a DVD case.

When these covers get sent to my Samsung F series, the images get resized (i'm guessing to 640x480) resulting in an incorrect aspect ratio on the screen

Is there a way that we can get the thumbs retain the correct aspect ratio when Mezzmo collects them for its database? Eg could it perhaps resize them to the maximum height (300->480) and then add black/transparent bars on the sides of the image?

Edit: Also, does the F series support going straight to the video folder, without having to display pictures/music/videos folders, if the video option is selected on the TV?
