dropped frames?

[Donald Hinkle]

I just got a new ALPB, with 60G HD, largely unused. BUT I'm importing 
video from my vidcam--something that never caused problems before--and 
getting halts, skips, delays.
Where do I start looking for a fix?
I guess I could move the camera to the iMac or the iBook--both of which 
imported movies just fine before. But I'd like to have it fixed on 
this, which should be the fastest movie-maker of all. Could it be that 
the Hard drive isn't fast enough, tho the computer is? Or can I find a 
6-to-9 pin cable that would connect to the faster Firewire port? (but 
why would I need to when the "old" one works fine on the iBook?)

You can see that my tek knowledge is pretty scant.
