Does anyone know why the sync on my film sems out when IO burn to a double layer disc...I checked the avi...perfect but when I burn it seems out slightly in some places. I have also checked the pre-rendered files and they are perfectly synched...if it helps I am using a HP Media centre but because Architect doen't support double layer burning, I burn on WIN DVD. The original avi file is about 21 gigs and it comopresses to about 7
