Frequent interruptions when exporting to camcorder

Question

When I export an edited movie back to the camcorder (Sony DCR TRV 240E; DV IN/OUT) I get small interruptions (freezing or vertical shaking) in the picture frequently (once every 60 seconds (approx.)). These interruptions are not there in the editing mode they occur on the iMovie screen when exporting and gets on the tape. I have tried with another tape with the same result.
Later on tape the interruptions also influences the sound.
Has anyone encountered this?
I would be very grateful for help.

Answer 1

a) in your system prefs, there's a tool "File
vault".. that has to be OFF, editing video
b) is your project on internal drive, or on an
external..? is the ext. hd usb(2) connected? should
be firewire...
c) your internal drive should be "crowded" ~80% of
max. single-click on hd's icon, hit apple-i, have a
look....
Hi Karsten,
Vault is off and the project is on the internal drive. The internal drive was crowded; 93% used. But even after moving 30% and get 63% free space on the internal drive the symptom is still there.
The frequence is every 60 seconds. The magnitude of the interruption is varying.
Should I do something more after emptying the trash after copying/moving?
