Sony FX1 not syncing with Powerbook?

[chimpanzee]

I've been using a Sony FX1 with a 1.5Ghz Powerbook, using iMovie.

 

A/V -> DV set to ON

iLINK CONV set to ON (HDV -> DV)

 

[ Can someone clarify these settings for me? I haven't been able to get iMovie to digitize HD video..only downconverted DV ]

 

All of a sudden, iMovie can't communicate with the FX1.

 

I was doing an edit..digitized some video. Then, it quit syncing with the FX1. I have a Sony Digital8 camcorder..& it syncs to it fine.

 

Is there something wrong with the FX1, or are my settings wrong?

 

Someone suggested deleting the preferences file for iMovie. I tried it, but that didn't help.

 

I'm using the FX1 in a dusty environment (desert offroad racing):

[ see the Robby Gordon video ]

 

Maybe the FW connector is fouled up because of the dust?

 

I don't what's going on..

 

Any suggestions?
