Dokka〜n is actually in an awkward situation regarding video and audio quality. Season 1 and Sharp have Blu Rays. Motto at least has every episode as HDTV. The final and well-received season, however, only has HDTV episodes for 29-49. So I thought well, if we don't have HD episodes for the rest, why not go to the next-best source - the DVDs. With the right encoding knowledge, I'm sure you can make these look better than what we have now. At the very least, the audio is a straight upgrade over the files people are currently using. Note: The HDTV episodes have the preview and ED switched around over the other episodes. Preview first and then ED is the order used for the DVDs/Blu Rays. This is annoying in case you wanted to take the audio here and just mux it into the HDTV episodes. Another really neat thing here is the bonus content. They even included stuff from previous seasons, which is a super nice touch. Today is when the first episode of this wonderful season aired in 2002, by the way.
