Converting lpub tagged ldr files to a single mpd

[Philippe Hurbain]

I generally prefer to create my LPub building instructions from a collection of ldr files in the same folder (it's easier to find the right place to edit), but now I'd like to convert them into a single mpd file for distribution. Problem, the mpd (built with MPDCenter or MPDwizard) doesn't render correctly in LPub (pagination issues, callout converted back to simple submodels, page format modified from landscape to portrait and so on). Is this a known problem? how to solve it (I'd hate to have to scan and correct all pages again!)
