Hi Aboi,
when I started this issue I were where you are.
But after:
first, updating those drivers recomended by very clever people at this fora
second, uninstall and reinstall all CyberLink products
third, brought, installed and ran "Advanced Driver Updater" from Ashampoo (whitch found 16 outdated drivers).
I haven't had this halt problem with videoes with length at 7 to 8 minuts. (havent yet tried longer videoes yet)
I've seen another post about this issue where is was stated that the problem caused by too little memory.
Could this be your problem too.
Don't send any specifications for me - I am not HW-freak and don't understand them.
I do hope you'll get your problem solved.
I find PD9 an exciting program with many options, I also get lost and irritated when things don't work as they should.
Cheers, Anja
