The preloader option for publishing is not improving the time that the captivate video (flash) is shown, it suppose that shoulkd start playing the flash video faster but it is not. I tested using diffrenet settings like 0%, 10%, 50%, 100% and even leaving the checkbox uncheked and the behave to load and start showing the flash video is exactly the same. I did it using different speed connection like T1, 4 Mbps adn 10 Mbps and no change. I read in this forum that switching to captivate 7 should work and it's working exaclty in the same way, no changes, so is useless to switch.
The adobe help has no usefull information. Looking to know how to start playing flash video faster for captivate projects.
