What's the difference between Microsoft AVI and Microsoft DV AVI?

In Adobe Premier Pro, I can choose to save to Microsoft AVI or Microsoft DV AVI. What's the difference?

What's the difference between Microsoft AVI and Microsoft DV AVI?suzuki

Both formats save the file as an AVI file - no difference there. The difference is in the Codecs.

When you choose Microsoft AVI you can choose between different codecs. When choosing Microsoft DV AVI there is no choice for a codec - as it is the Microsoft DV codec, i.e. a DV25 codec.

I presume that if you purchase the Mainconcept DV codec, you can save your file as a "Microsoft AVI" and then choose the Mainconcept codec.

Why it is done in this way I find fairly strange - as it confuses people. Maybe the reason is that choosing any other codec but the DV codec makes Premiere re-encoding the whole project - while when choosing the DV codec is basically mean saving the project (as DV25 is the "native" codec for Premiere).
