I've never had much success converting HD unless I've used some sort of
pullup strategy, but I don't have a great variety of ways to import, so I
don't have any idea whether I can help you. I have a Hauppauge HD-PVR, and
this weekend I tried some of my pullup methods on the 1920X1080 output from
that. But it's a little hard to insure that I have a clean source, and if
the source isn't fairly clean, I can't tell what method to use on it. But
when the source is clean and the method is correct, I can't imagine any
conversion tool yielding better results than those I get with MEncoder. I
used to use the pullup filter, but lately have had more success with
filmdint. Have you tried anything like that? Maybe you could make an excerpt
of your source available, say in the neighborhood of 100 megabytes.
