Perhaps try removing CCCP and replacing it with Shark's codec pack.
I always prefered CCCP for XP, but for Vista and 7, Shark's seems the better one to go for.
Not to mention a lot of it can be controlled directly through the Shark Codec Pack UI so its a little simpler to navigate sometimes, and you might find it a little easier to alter settings without having to dig around due to the shortcuts etc.
PS. generally the Mazui sub of S&WII is better, common perception is that Frostii dont seem to like Lawrence that much, so he comes across as less likeable due to the way they translated it and coloured his lines during the process [apparently also alter the wording in several critical points which gives the scenes less impact than they deserve]. Aside from slight annoyances with the last episode, the Mazui sub is actually pretty decent anyway
