Final cut 5 HD capturing

How do I capture HDR-FX1 footage on Final cut pro 5. What are my capture settings and sequence settings. I shot the footage in 1080i mode and I am finnishing on Beta SP as a master.

Also I have a music video that is shot in two different formats. One format is HDR-FX1 shot at 1080i and the other is the SDX 900 which we shot DVPRO 50 at 24p. The resolution is video 720:480 but the DVCPRO 50 compressor produces a mucher higher qulity image. My problem is when editng this footage together, which format should I edit at, meaning should my edit sequence be set for 1080i editing or sould it be DVCPRO editing setting..

thanks Role

I started out with a G4 and Final Cut Pro 3. From there I upgraded to 4.0, 4 HD, 5 HD. I was able to download my Sony Z1U Shot in1080i60 High Definition Camera even though my G4 was a little slow with that much information ? It worked. Along with my G4, I just purchased my G5. I used the same settings as my G4 and tried to download and could only get 3 to 4 minutes before the download screen froze. I have changed settings, I tried many different things and it continues to freeze up.
