With the 7d, if I shoot in 24p can I mix that footage with a 25p in a timeline in FCP?

Also, is there any recommended way of mixing HDV 1080i footage with the aforementioned 24p and 25p footage from the 7d?

Thanks for any help!!!

Cineform Neoscene may have the answer to your questions.

Wow, I hate those type of projects. I'd either convert everything first into either a progressive or interlaced format. You can then use cinema tools and match footage speeds until you have to render. What is final delivery format? Web?
