Just to update the thread, got the bluray drive off my brother and a few discs, first thing i did was update the firmware on it, tried putting a disc in and it wasnt even trying to read it, all other discs we tried were reading ok, then i found on net a list of compatible dual layer bd-r discs compatible with his drive and the discs he had werent on it, so can only assume its the discs, i did advise him to get verbs in the first place as there a very good disc imo, there also on the list i found tonight so hes going to order some of them and all should be ok, thanks
