Ever since the last QT update 7.6, my AVIs are so pixelated to the point where it's no use for me to edit them in FCP. They're more like thick white blocks that completely distort the image. I have both Perian and Flip4Mac up to date. I'm also using MPEG Streamclip to convert to a more friendly h.264 clip. I've seen this mentioned in other Mac forums but none here in greater detail. Anyone else experiencing this issue?
