The Shield- which version to get?

[LeSamourai.]

Hello,

I've never watched The Shield. I'd like to get the whole series but have read about various scenes being cut throughout the series, including 20 minutes from an episode (Postpartum, I think it was called). I cannot get the UK set for this reason.

I've also read that the US blu-ray is cut and that the aspect ratio is incorrect. Are the US DVDs uncut and in the correct aspect ratio?

I'm not fussed about HD vs SD; the priority for me is to watch the uncensored/uncut episode in their correct aspect ratios. Which is best for this?

Thank you.
