WHY do I still have to render? at DVinfo.net

Hi all you gurus!
I thought I understood this . . . but apparently not! We have an XF300 and an XF100. Outstanding cameras. (And yes, we have Doug's training DVD's!) Usually I shoot in 1280x720 30p, because I overcrank a lot. We work with the latest and greatest Apple computers and Final Cut Pro. If I import NATIVE (yes, that works now, thank you Canon) in the 720 mode and create a new sequence in FCPro, if the sequence doesn't match the above clips - we get the normal "Sequence doesn't match clip - do you want to change it" sign. Good. We make them match - and never need to render clips shot and imported that way.

Now let's do the same thing shooting 1920x1080 60i. We shoot that way, set up a new Sequence in FCPro, and drag one of those clips on the sequence Time line. FCPro asks the same message, do we want to match, etc - I click yes and it puts the clip on the timeline. The codec is "XDCAM HD422 1080i60 50mbs" which is, I think exactly what it should be. The clip doesn't "look" like it wants to be rendered - that is there is a grey bar on the top of the timeline. But if we highlight the clip and hit "Command +R" it will want to render it. Takes quite awhile to render. Sometimes it'll render faster (don't understand this either) but will always want to render.
But WHY? The timeline was setup to that clip - it shouldn't need to render?
Anyone have any ideas?
Thanks,
Larry
