Motion JPEG is actually preferable for video editing, since it is an "intraframe" codec, meaning each frame is compressed individually. This allows it to be edited more easily, in particular, avoiding generation losses when you render effects. The tradeoff is that file sizes are larger, but generally, the quality is better.
As one example, if you want to edit long-GOP media (e.g., HDV, MPEG2, etc.), you have to re-encode around each cut point, which degrades your image quality. MJPEG doesn't require that; you can cut clips together all day long without requiring re-encoding.
