Problem with capture

[Axxtro]

So I recently got everything up and running with a wii and a capture card, but noticed that the quality was weird. Sometimes it was fine and sometimes it was not and I noticed that the quality actually change when im moving between loading zones. See video.

Im using homebrew channel on a white pal wii and installed sm64 with a wad file. It works perfect on the tv but not on the captured image. The capture card is an Elgato HD60. I've played around with the settings but without success.

It woks if I emulate it with wii64 but that brings other problems.
