I tried to use the OPV mode (v0.62) in combination with the half-D1 option for the extras. In this case, the Q analysing prozess stops with the Errorcode 53 (file not found) when the extras-vts is reached. The same DVD with the options with vbr is OK. I tried many differend DVDs, but every time the same. Whithout the half-d1 option the OPV mode is OK, no Errorcode ?? Is it a bug or is this combination not possible ??
