Your problem is that V210 is a raw format. There are no interlacing flags in V210. You also want to write using the AVI container; AVI does not explicitly support interlacing. You can dump interlaced frames to AVI but without prior knowledge or visual inspection there is no way for software to know.

On the other hand QuickTime mov format supports interlacing, this is the reason why you had success with it.
