DNLA Thumbnails Squished

Recently got the PR4100 as it uses Twonky for its DNLS and I just a few months prior bought Twonky for my PC and liked it and understood the config settings.

I guess its OK that the PR4100 Twonky config settings are not as robust as the full product, but I am having an issue with the generated Thumbnails. I have a mix of 16x9 and 4x3 content and on my Roku via the PC version of Twonky the thumbs look as expected - either full 16x9 or pillarboxed for the 4x3 content. But on the PR4100 all content is squished in from the sides and doesn’t look good.

Any suggestions on how to fix?
