I’ve been having the same problem.
Here are my specs:
SD project with a DV AVI video file. I have about 20 audio tracks.
At first it would crash on me during playback, as well as the playback being jittery – some times froze on frames but audio would continue – in the Standard Def format.
I imported the project into a new one, same problem. I attempted to copy the timeline to a new one, crashes due to limited memory available.
Now I can’t even export the audio without it crashing or giving me the unknown error. I even tried reinstalling. I have all the updates for CS3 but still does not help.
Comp:
AMD Athelon 64 3.2 Ghz
2gig RAM
Avialable Disk space 156GB on a SATA Drive.
Very confused, I am attempting to get this project done and wont be able to if this continues.
