RE: Horizontal lines
First remember that interlaced material is not drawing a full frame at a time. It is only half a frame so you will notice horizontal lines. When producing output for the web or a computer, you should de-interlace the output. I use the QuickTime export for that. If you are exporting to create a DVD via iDVD, then the de-interlacing step shouldn't be needed since DVDs are interlaced material.
The other thing I can think of is a worse case scenario. iMovie 7,8 and maybe 9 have an issue with DV interlaced material. I found the problem being discussed on this very long thread at Apple; Apple - Support - Discussions - DV video quality ...
A possible solution to that problem was posted here; The iMovie Output Project
As for the choppy or short clips, I don't have an answer. Potentially your import is not clean and is dropping frames. It is best to capture to drive other than your internal one, although I have captured to an internal one with success. I could speculate a little further but don't want to write a guessing book.
