Fraps Only??
 

Are there any other software packages like fraps that Can be used to make wow or Frozen Throne Videos?

Are Fraps vids the only Vids accepted for some reason?

I have video editing software, But Im looking for recomendations for Video Capturing!

Well, Fraps is the best one by far, but there are alternatives... one named GameCam that costs a bunch of money and I personally kinda like one thing they have which let's you always have the past ~certain amount of minutes~ recorded, so that you can have it running all the time and then after you get something good you pause it and save it (so that it doesnt take up so much harddrive space trying to get good material if you're doing Arenas for example)

Another alternative is the video recoding that Xfire has, I think it's free and I havent really tried it out much.

But there is nothing that comes close to the performance and quality of Fraps, so that's why people use it
