Looks really nice, thank you.

But I think that some of the article doesn't meet the wiki standards, in example you write in a sentence "I didn't nailed it down." where in wiki there shouldn't be any "I", especially because the poster is unknown and the article should be written by many users.

Also, "The two codecs that most people will consider" in wiki there shouldn't any "most", its called weasle words.

I'm editing it a bit now, but there are more sentences to be changed for the article to meet the standards, but I'm not that good with English.
