Hi
Tried several ways managed to write dual layer dvd BUT on playbback they lockout at the layer switch point. I can skip this point with next chapter search but obviously that is not acceptable - could it be a media problem method as follows
1 dvd author to mak film base (menus)
1 dvdshrink to make iso of dvd film files from the audio_ts and video_ts folders
2 used dvddecrypter to write the iso file
samsung ts-h552u writer
rw rivision dvd+r dl media
now frustrated
