That's encouraging! I'll go back tonight and line up the Deems Taylor narration and put up the new version and the Sorcerer's Apprentice (I'm not working in order of screen time, but rather in order of easiness!)
It looks like I may have to replace the Kostal orchestration with the Stokowski for a couple of seconds during the Pastoral; for some reason, the Kostal is cut oddly and missing two seconds. :S
