Help:

I am using Ulead Video Studio 9, 3 G processor 512 MB Ram, I capture from my Video with S-Viodeo to VCD format (MPEG), but after I have finished editing I cannot transfer it into video file or to CD, my computer stocks within 18% of creating file.
This never happen when I use to caputer via USB in avi file, note that when I edit I used loads of slow motion.

Any one help me?
Thanks
