Does its own manual not say?
My very honest view is that for editing where you need to have some degree of control over audio and video in separate tracks, apply track specific effects 9 or corrections). The likes of VS ( and Pinnacle Studio are more lacking or have less fine control) than Adobe Premirere Element s or Sony Vegas Movie Studio whose roots from more grown up video editing packages make a/b roll type editing a breeze. Ulead stopped making Media Studio a long time ago. Even DVD Movie Workshop was also stopped
None the less you could try Uleads own user forums
Brian110507 ( a now quiet member here who is of a VS expert) seems not to have his ulead VS website up anymore. If there is anything he doesnt know about Ulead VS , its probably not worth knowing. He might just respond to PM
I think Ive seen him Mod the Ulead forums in SimplyDV ( which you can google )
But look
