Final Cut Express


1. I tried to trim a few frames from the front of a sequence in the timeline. After that, every time I stop motion in the canvas, the frame is pixelated and garbagey. Not just in the sequence I did it in but all sequences. I've tried rendering, even though everything was rendered, and that did nothing. closed the program and re started it, reverted to saved, and nothing changes, still garbage. If i view "image+wireframe" it goes away, but only with the wireframe.
2. is there any way to slip the audio track imported from a CD (non-commercial, non-protected) a few frames to sync it with video without having to render it after every try?
