I'm not sure what your talking about. The only thing Google comes up with for what a field blend is wine related.

You have to remember with TV content we are in the PAL region, but Transformers was made in the US where they use NTSC which means both the frame rate and resolution are different. In order for Madman or anyone else to transfer content from NTSC to PAL a frame rate change and resolution change is normal on DVD as it is SD and follows the PAL and NTSC standards. This creates artefacts in the encode, it is unavoidable unless you make a Blu-ray which can change it's frame rate to 24 (film), 25 (PAL), 30 (NTSC) and 60 frames per second as the content dictates.

If you want NTCS produced video without any conversion artefacts you need to buy the US DVD or a Blu-ray if it exist.

I should probably also point out that I tried ripping my Madman release of the Remastered version to play on my Xbox One via DLNA and found that MakeMKV could not separate the episodes and the image was stretched out to a 16:9 image.
