MJPEG has different quality levels. So it could be better, same or worse than DV. Depends on the setting that is used in the camera.
What sort of camera is it?
You might just have to take some footage and see for yourself.

AVI is everything, M-Jpeg is just a codec used to store the video in the AVI, so you always will get an avi.
If you're using a cam-corder, then only use m-jpeg if you're sure if it is an analogue camcorder and it cannot create DV (DV also is a codec, but always delivers better quality than m-jpeg!), otherwise use the DV-codec.

The main differance between DV and m-Jpeg is that mjpeg does more video-compression (that's also why you get worse quality if you've got the possibility to use DV).
DV usually is a vast data-rate (at 3.5MB/sec), while mjpeg mostly uses a much lower bitrate (so some diskspace is also required with DV).
