There's no way we can know what to do without seeing a clip, but it's
probably going to be very difficult to clean it up well..

For converting interlaced content from DV to DVD, be _SURE_ you get
the field order right. If not you will get very stuttery motion. Some
people who don't know about this make such DVDs and assume it's
normal, and of course the results are very painful to watch.

Ah, here are the samples.. Hmm.. All I can suggest is some fairly
strong denoising, perhaps followed by a good sharpening filter.
Unfortunately mencoder lacks good sharpeners.. :( The second one is
very dark and will be difficult to do much with. If the denoising goes
well enough it might be possible to stretch the contrast, but I
imagine it will horribly amplify noise.

Here's an idea: try taking those still pics and loading them in gimp,
and see if you can get them to look good as stills. If so, tell us
what gimp filters you use to fix them, and we might be able to suggest
some good filters to do the same on video with mencoder..
