Nah, not really. I've never had the issue anymore with my new pc and CS4.
I have tried CS4 but when exporting the media encoder didn't show and i couldn't export the video, and i heard that CS4 is worse than CS3 and needs new processor.
Not sure what you mean with these. Like I said, I've edited with 26 scripts and more loaded at the same time and exported just fine. It really goes from vid to vid and from pc to pc...
So it all depends on luck? O.o
If you have intention to get a new pc, you should really think about getting a desktop. Possibly along with a TBs worth of HDD space, so you could just use lossless files to edit.
I can't buy a desktop, i travel a lot and i need a laptop to take it with me so i can edit wherever i am. So if i'm going to buy a new laptop how much RAM and velocity may be good? Space isn't my problem, i have 1 TB external hard disk i think it's enough for losses AVI. Do losses AVI make problems too?
I tried exporting with the losses AVI files but i got something weird in the clip:
The first time i exported it appeared in other clip now it appeared here, why is that?
