Andrea, I think I have caught up with you now. So far have done the same as recommended by Andrew):
1) move patch2 (for now)
2) delete patch4 (not needed anymore)
3) added ONLY the patch from Andrew as listed below (if you have trouble with this, I can send the 2 whole files instead).
4) am now at the bdwrite and lv2ui errors like you; will work on these tomorrow
