How to remove 24pa pulldown?

Hello, my first post as a new CS6 user coming from FCP7. So far I'm loving it.

Here's the thing; I dragged some 24pa footage off a HVX200a P2 card onto the disc then imported to a 1080/23.98 timeline.

All looked great until I applied the warp stabilizer or the C2 lock&load stabilizer plug-in then everything went crazy not stable at all.

I looked at the file properties and it said Frame Rate: 29.97 (24p) and I assumed the 24p was the pulldown removed.

I captured the same fooage through FCP's capture window that has a dedicated pulldown removal button then imported that.

The properties show Frame Rate: 23.976 and the filters work fine.

Can you tell me what I'm missing please?

Thanks.
