Thanks for the quick response guys.
I tried all your suggestions.
No luck.
The machine is a 12 inch aluminium Powerbook G4 running OS 10.4.9
The fault started on FCP 5.1.
I am now running my old trusty FCP 4.0.1.
I played back from my DSR 11, so I switched to the Sony HVR Z1E camera and get the same fault.
I played the stuff into my old G4 titanium and my G5 desktop system with no problem.
Changed destination hard drives as well.
I do not gt the tearing that you mentioned, but a picture freeze for about 4 seconds. It then continues to digitize and the audio is out of sync by the amount of time it remained frozen.
Could it be a Quicktime issue?
The strange thing is that I have been using the laptop on the road from Baghdad to Bangkok for at least 2 years with no problem( except for a change of hard drive 8 months ago).
The chicken is now cooking so I did get something out of it.
Cheers
