Robert-
I have the same problem which started about a week ago — capture freezes at about 5 minutes. I’ve went through tons of diagnostics — different decks, tapes, hard-drives, reloaded FCP, etc. None helped.
I’ve been using FCP 4.5 HD on a powerbook g4 with no problems for 3 years and this has me dumbfounded.
Seeing your post leads me to believe there has been an update somewhere, quicktime, os, etc. that is doing something to FCP.
Any solutions yet.
Help!
I’ll let you know if I find anything out.
Thanks.
