1 shiidii -- That seems to be "CD" (though there's no di in Japanese, so it should be shiijii)
kaa -- sounds like "car"
wanman-kaa -- "one-man car"?
takushi -- sounds like "taxi"

Ooba [kooto] -- OVA [cut]?

Also think that "uetto" from "uetto na kanji" could be "wet" but it sounds very strange (wet kanji?).

3 "takushii" （タクシー） is taxi

"kaa" （カー） is car

"shiidii" （シーディー） is CD. Also, as a note to Jaked, the (ディ) katakana compound with the small イ is generally used to represent an actual "di" sound. That's how CD is spelled in katakana, and most Japanese people pronounce it that way, so saying there is "no di in Japanese" is a somewhat misleading statement.

"wanmankaa" （ワンマンカー） is "one-man car". This refers to a bus or a train with only one employee - the driver, who also acts as the ticket collector or conductor.

in "uetto na kanji" （ウエットな感じ） is an English loanword, "wet". Although I can't be entirely certain without context, the most likely interpretation is the phrase "a wet feeling" or "wet sensation".

"ooba kooto" （オーバコート？） I haven't heard before, but it could be "overcoat".

Oh, yeah, I know about that, but in my experience, and I mean, at least with all the Japanese I've encountered they always pronounce it as ji instead of di. I guess it's due being so accustomed to it. (Thinking about it, there's no di I can remember on anime either, but then again I haven't watched any recent ones or the old ones that do pronounce it, if they do exist. I'm guessing they don't but if they can as you say I wonder if they have guidelines as to how to dub anime in Japan)

Overcoat -- that sounds much better but I wonder about the brackets "[]" around kooto.

5 I will forward those to my correspondent. Thank you for your help!

6 Sorry for the off-topic, just wanted to point out that since yesterday morning has been the same pic up there of Aria the Animation's girl on pink, one-piece swmsuit. Got nothing against it (quite cool actually) but doesn't the pic up there changes like every hour or something?

7 Try to get some context for each one.
Like have him use it in a sentence, 

8 Jaked, yes it does, and yes it has been. Try clearing your browser cache. (Right now it's a picture of one of the twins from Negima!?)

9 The thing is, I noticed it not because of my desktop but because it "happened" in several computers at my college throughout yesterday and today. I guess I just had some weird luck then.

Ooba Kooto is the new show by Production IG about the Oboe player and the Koto player who, practice together, become an eclectic musical hit, tour the world and fight crime.

11 "Naisu In" appears to be used to compliment a golfer: "nice in". There's also at least one "Nice Inn" hotel in Japan.

"Uetto-na kanji" shows up on fashion sites to describe "wet-look" hairstyles (as opposed to "dorai"). There are other uses I didn't track down.

"Goo sutoppu" is a Korean card game, whose rules include a continue/stop condition.

"geemu setto" is from tennis: "game and set".

12 Actually....I made that last one up.
