Trouble burning HD DVD in DVD Studio

FCS 7. Ready to burn a HD DVD but getting message "The Build Location folder contains a VIDEO_TS folder(standard DVD content). You must remove the VIDEO_TS folder from the Build Location in order to proceed with Build/Format of a HD DVD project."

The help info says I should have choice of VIDEO_TS or HVDVD_TS. I go to Format but see nothing about HVDVD_TS and can't figure out how to remove VIDEO_TS from the Build Location as instructed.

The default build location is ~/Library/Caches/DVD Studio Pro Files. Clear out the contents of this folder and you should be fine.

My software:
Pro Maintenance Tools - Tools to keep Final Cut Studio, Final Cut Pro X, Avid Media Composer and Adobe Premiere Pro running smoothly and fix problems when they arise
Pro Media Tools - Edit QuickTime chapters and metadata, detect gamma shifts, edit markers, watch renders and more
