  In general, I agree with the way you did your experiments but:

    1. You shouldn't be doing deinterlancing. There are very few
       tools for that to handle PAL chroma issues correctly.

    2. The only format that doesn't screw up PAL chroma right away
       is YUV4MPEG. So you should be using it instead of PNG to
       store the output of the DV decoders. 

    3. You might find it usefull to try commercial DV codecs by the
       virtue of MPlayer .dll handling.

Thanks,
Roman.
