I tried putting all the files I needed into another project folder. Same result. However, as I stated earlier, it worked on my wifes laptop which is not near as good a system as mine from the information downloaded to a flash card. There is a treansition there (overlap) at the sticking point and I removed it and the production continued to 99% (less than one second to go) and it froze again?! Yes there is also a change in cameras there as well, but like I said this all works with less than half the cmputing power on my wifes laptop.
I have tried producing it in MPEG-4 best quality and H.264 avc 1920x1090. Again these worked on the other computer.
Any more ideas?
Thanks
