The chapter divisions for the Psalms in VUO contain many errors. If you have the psalms divided in the correct place, you may want to send them to the programmers, for possible inclusion in VUO.
I have worked up a verse map file for the psalms in VUO, which I can easily make into a separate .vmf file, depending on where your file divides the psalms.
If you are making your own .vmf file, be sure that you compile your Latin Psalms as "OT only" not as "Custom". And be sure that you map the psalms to WTT and not to BGT or any other version. If you do those things, your .vmf file should work fine. If not, you can e-mail it to me, and I can take a look at it. But it may be a few weeks before I have the time.
