Thanks for the pretty pictures, but they're not all that helpful.
I will say this: you can't expect miracles out of PAL DV Widescreen in the first place: there just isn't much resolution in the images in the first place. Beyond that, you'll need to help us help you:
I'm with Dave on this one, don't expect miracles out of PAL DV. However, if your on Mac, I would suggest Quicktime and Apple ProRes 422 codec. I usually use this to get good results out of a render.
You can also try Adobe Media Encoder and go for a h.264 with a good bitrate.
Now, these facts are not backed by any hard evidence with numbers haha, it's just what I usually go for and it works fine
