I would love to see a better version of Hikaru No Go offered, if one actually exists. Without looking at aniDB, I don't know off the top of my head if one does.
As for the dual audio version, it's not S-A's fault that they are stalled at episode 45, it's Viz Media's. They've pretty much canceled the DVD releases, so good luck on ever getting the last third of the series dubbed in English. Viz has started to release the episodes that they didn't release on DVD on Hulu, however, but they are only subtitled. Considering that it sold pretty poorly in the US, I doubt they will finish releasing the dub (as far as I know, it's completed), on DVD, but they might (still doubting it) release it through streaming.
I'm somewhat curious if Viz's streams are of higher quality than the TV rips that are currently on the site. Those sub releases are pretty ancient, back from the days of the Hikaru no Go FTP Archive (I'm sure Zalis remembers that

).
