The blue bricks are good enough. I have pretty low standards for a cartoon from the cheapest animation studio still around.
As long as it's uncut and 4:3 I'm satisfied. Strangest thing to me is when streaming the show on their website the sources seem to be completely different depending on what language you choose! Cropping is equal, but the dub video track looks far - far - superior. If you watch the sub, the colors (especially red, which is already a problem with their masters) bleed like crazy and the blacks get even more crushed. I have no possible explanation for this, and my attempts to take screenshots seem to be a lost cause.
