Not ideal, but it may be an acceptable workaround. Other alternatives I've come up with:
1) Manually create a few hundred auto-playlists to break down my 14k artists into smaller chunks. This would be a lot easier if the advanced search in autoplaylists were even more advanced.

2) Rip all my CDs to regular FLAC tracks and get rid of all my Virtual CDs altogether.
3) Ignore DLNA until MM introduces better navigation and/or conforms better to DLNA specs.
A difficult choice!
