You could try adding --ignorebadprefix to mklocal.py but you'd probably then need to run it multiple times for each path you have in your library - to be honest I haven't really tested it with multiple paths as I don't have any of those.

You can also filter the input with something like texturecache.py jd movies @filter=path f:\Movies so that only the movies from f:\Movies are processed by mklocal.py --prefix f:\Movies. Obviously you'll need to change the call to texturecache.py for each of your paths, and update mklocal.py accordingly.
