Split-by-Scene in VS10 +

[Amalthia]

In VS 8/9 it only took about 30 minutes to scan a 45 minute video and split-by-scene in my library. In Ulead VS10 + it's taking over 2 hours to do the same thing with the exact same video files.

I'm not sure if I'm doing something wrong in VS10+ or if anyone has figured out why it takes twice as long to split-by-scene as it did for UVS8/9?

I'll really appreciate any and all help,
Amalthia
