I shot a commercial on 35mm and I send in the film to the lab and they scanned it in on a D-5 tape. I've got a D-5 deck, but I want to downrez it to an HD thats more manageable bit rate for FCP
You can try a method I use for down converting HD to dvd:
-Open FCP and create a new project > sequence
-Right click on the sequence in the browser and set the settings to match whatever you want
-Any footage you the capture into FCP you can drag into this new sequence and FCP will automatically resize the footage for you. If a pop up asks to make the sequence fit the clip size say no.
