You can only notice the interlacing stripes when the picture - or better the objects in the picture - move with a certain speed, that's why the logo doesn't appear to be affected.
An interlaced picture is set together by two half frames. Every second stripe or line in the picture comes from frame A, the other ones from frame B. Imagine frame B is set some milliseconds later than frame A. When copied together and you have a fast moving scene, the B lines don't match the A lines that well anymore. If you have a slow paced scene or a freezed image, you wouldn't even notice it.
If you've got the chance, try to watch the trailer on an older CRT TV model and you will see that the picture appears to be normal (don't know if this also works on LCD or plasma TVs), since interlaced video was an old standard for those TVs.
I hope you could get any sense out of my explanation, since I'm German and I'm not too sure of my English qualities when it comes to explaining such technical details
Anyway, this clip clearly is interlaced, the others are not, I can confirm that.
