dual layer write - samsung ts-h552u

[ancient]

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
