Dear all Maybe it will be useful for someone. Please find attached a patch I made, gathering patch made by other people (especialy from Fabian Keil in an email from Sat, 14 Jul 2012). I added on it an additionnal check (ptt[i].pgcn-1 >= ifo->vts_pgcit->nr_of_pgci_srp) that helps reading one of my broken ripped DVD. Regards Vincent
