I have just uploaded ExPVR V3.7 to http://www.ph-mb.com/products/ExPVR/downloads. This version contains a rewritten database engine which fixes the issues concerning the new Picasso firmware. There are additionally quite a few bug fixes and some improvements to the copy process and UI.
The issue with pre-darwin to picasso copies (viewtopic.php?f=6&t=626) has now been fixed and there is now full support for the new picasso features (e.g. the un-deletion support).
Please visit http://www.ph-mb.com/products/ExPVR/change-log for a full change log.
