Update- deinterlacing film originated project- not working

Thanks everyone for the help before. For those who didn't read the thread before, I'm trying to deinterlace the 16mm footage I got from the lab after they transfered it to mini dvcam.
I spoke with the lab today and here's what they told me:
They convert the material to ntsc 60i via the 3:2 method and I'd need to use that (rather than 3:2:2:3) and treat it the same as dvx100 stuff shot at 24p (not 24pA). They said they marked a frame with a black circle that should be where I start the deinterlacing from.
I've tried rendering from that spot (from already captured material) but it's not working that well. If I render with any setting with "blend fields" I get a very blurry result. Using deinterlace method "none" is not as blurry, but, if I chose rendering to "Best" it still is blurry. Rendering to "good" or "preview" looks a bit better. Still, any way I do it I still see the occasional frame with interlacing or sort of a ghosted interlaced frame. Rendering to uncompressed doesn't help.
Can anyone tell me what I'm doing wrong? Is this something that has to be done when capturing?
Sorry for the long post, but this is important to be as I need to do some bezier masking. Thanks for any help!

Did you ever try the DVFilm Maker version 2 conversion? I know you had a bad experience with version 1, but it seems that this utility is meant exactly for this type of thing.

If you start a 24P project in Vegas then import your pulldown video, does that work? Isn't that supposed to drop the pulldown frames rather than deinterlace?

I've noticed that the latest version of PowerDVD (5) has two different deinterlace methods: "bob" and "weave". "Weave" is supposed to get rid of the extra pulldown frames during playback. Maybe you could capture the out-put of that via an s-video output if your graphics card has one.

Thanks, Laurence. I didn't try the DVFilmmaker yet as I thought Vegas would do the same 2:3 removal as DVFilmmaker would. I just tried copying and pasting a clip into a 24p timeline, but that didn't work either.
I just looked over the Sony white paper on the dvx100 and can't find anything about pulldown removal when capturing. I'm beginning to think I'm going crazy.
Is there a way to do this?

Thank goodness!! What you have to do is right click on the clip from the Media Pool and select file format properties. Then you check the box for enable 2-3 pulldown. There's usually a bit of tinkering to be done finding the frame to off set, but once you put the event on the timeline you can see right away if you've got the right one selected. This part was easy for the event I used as I went to the event I'd already rendered from the mark the lab told me to look for.
Think there's still some tinkering to do here with making subclips and what not to make the offset correct, but I'll deal with that tomorrow.
Once I'm done with the bezier masking, then I'm thinking is the time to render to "NTSC DV inserting 2:3 pulldown" so I can then add it to my main project, the material of which has not been deinterlaced.
Learn something every day.

I just checked out what you said. Very cool indeed!
