We ran into a small problem with converting Video files to KMA... they took ~12 seconds to open before playing.
We are taking another approach that will use a "new" KMV or KMH format (versus KMA) and should convert all the above video files at light-speed to this format, then they should play within a short period... fraction of a second we hope.
We were trying to get this upgrade in 4.03, but the out-of-sync problem has taken our 100% attention yet again.

We think we will solve it once and for all this time.
